Improve integration testing client (CodexClient) and json serialization (#514)
* Improve integration testing client (CodexClient) and json serialization

The current client used for integration testing against the REST endpoints for Codex accepts and passes primitive types. This caused a hard to diagnose bug where a `uint` was not being deserialized correctly.

In addition, the json de/serializing done between the CodexClient and REST client was not easy to read and was not tested.

These changes bring non-primitive types to most of the CodexClient functions, allowing us to lean on the compiler to ensure we're providing correct typings. More importantly, a json de/serialization util was created as a drop-in replacement for the std/json lib, with the main two differences being that field serialization is opt-in (instead of opt-out as in the case of json_serialization) and serialization errors are captured and logged, making debugging serialization issues much easier.

* Update integration test to use nodes=2 and tolerance=1

* clean up

Slot queue (#455)
## Slot queue
Adds a slot queue, as per the [slot queue design](https://github.com/codex-storage/codex-research/blob/master/design/sales.md#slot-queue).

Any time storage is requested, all slots from that request are immediately added to the queue. Finished, Canclled, Failed requests remove all slots with that request id from the queue. SlotFreed events add a new slot to the queue and SlotFilled events remove the slot from the queue. This allows popping of a slot each time one is processed, making things much simpler.

When an entire request of slots is added to the queue, the slot indices are shuffled randomly to hopefully prevent nodes that pick up the same storage requested event from clashing on the first processed slot index. This allowed removal of assigning a random slot index in the SalePreparing state and it also ensured that all SalesAgents will have a slot index assigned to them at the start thus the removal of the optional slotIndex.

Remove slotId from SlotFreed event as it was not being used. RequestId and slotIndex were added to the SlotFreed event earlier and those are now being used

The slot queue invariant that prioritises queue items added to the queue relies on a scoring mechanism to sort them based on the [sort order in the design document](https://github.com/codex-storage/codex-research/blob/master/design/sales.md#sort-order).

When a storage request is handled by the sales module, a slot index was randomly assigned and then the slot was filled. Now, a random slot index is only assigned when adding an entire request to the slot queue. Additionally, the slot is checked that its state is `SlotState.Free` before continuing with the download process.

SlotQueue should always ensure the underlying AsyncHeapQueue has one less than the maximum items, ensuring the SlotQueue can always have space to add an additional item regardless if it’s full or not.

Constructing `SlotQueue.workers` in `SlotQueue.new` calls `newAsyncQueue` which causes side effects, so the construction call had to be moved to `SlotQueue.start`.

Prevent loading request from contract (network request) if there is an existing item in queue for that request.

Check availability before adding request to queue.

Add ability to query market contract for past events. When new availabilities are added, the `onReservationAdded` callback is triggered in which past `StorageRequested` events are queried, and those slots are added to the queue (filtered by availability on `push` and filtered by state in `SalePreparing`).

#### Request Workers
Limit the concurrent requests being processed in the queue by using a limited pool of workers (default = 3). Workers are in a data structure of type `AsyncQueue[SlotQueueWorker]`. This allows us to await a `popFirst` for available workers inside of the main SlotQueue event loop

Add an `onCleanUp` that stops the agents and removes them from the sales module agent list. `onCleanUp` is called from sales end states (eg ignored, cancelled, finished, failed, errored).

Add a `doneProcessing` future to `SlotQueueWorker` to be completed in the `OnProcessSlot` callback. Each `doneProcessing` future created is cancelled and awaited in `SlotQueue.stop` (thanks to `TrackableFuturees`), which forced `stop` to become async.
  - Cancel dispatched workers and the `onProcessSlot` callbacks, prevents zombie callbacks

#### Add TrackableFutures
Allow tracking of futures in a module so they can be cancelled at a later time. Useful for asyncSpawned futures, but works for any future.

### Sales module
The sales module needed to subscribe to request events to ensure that the request queue was managed correctly on each event. In the process of doing this, the sales agents were updated to avoid subscribing to events in each agent, and instead dispatch received events from the sales module to all created sales agents. This would prevent memory leaks on having too many eventemitters subscribed to.
  - prevent removal of agents from sales module while stopping, otherwise the agents seq len is modified while iterating

An additional sales agent state was added, `SalePreparing`, that handles all state machine setup, such as retrieving the request and subscribing to events that were previously in the `SaleDownloading` state.

Once agents have parked in an end state (eg ignored, cancelled, finished, failed, errored), they were not getting cleaned up and the sales module was keeping a handle on their reference. An `onCleanUp` callback was created to be called after the state machine enters an end state, which could prevent a memory leak if the number of requests coming in is high.

Move the SalesAgent callback raises pragmas from the Sales module to the proc definition in SalesAgent. This avoids having to catch `Exception`.
  - remove unneeded error handling as pragmas were moved

Move sales.subscriptions from an object containing named subscriptions to a `seq[Subscription]` directly on the sales object.

Sales tests: shut down repo after sales stop, to fix SIGABRT in CI

### Add async Promise API
  - modelled after JavaScript Promise API
  - alternative to `asyncSpawn` that allows handling of async calls in a synchronous context (including access to the synchronous closure) with less additional procs to be declared
  - Write less code, catch errors that would otherwise defect in asyncspawn, and execute a callback after completion
  - Add cancellation callbacks to utils/then, ensuring cancellations are handled properly

## Dependencies
- bump codex-contracts-eth to support slot queue (https://github.com/codex-storage/codex-contracts-eth/pull/61)
- bump nim-ethers to 0.5.0
- Bump nim-json-rpc submodule to 0bf2bcb

Validator (#387)
* [contracts] Add SlotFreed event

* [integration] allow test node to be stopped twice

* [cli] add --validator option

* [contracts] remove dead code

* [contracts] instantiate OnChainMarket and OnChainClock only once

* [contracts] add Validation

* [sales] remove duplicate import

* [market] add missing import

* [market] subscribe to all SlotFilled events

* [market] add freeSlot()

* [sales] fix warnings

* [market] subscribe to SlotFreed events

* [contracts] fix warning

* [validator] keep track of filled slots

* [validation] remove slots that have ended

* [proving] absorb Proofs into Market

Both Proofs and Market are abstractions around
the Marketplace contract, having them separately
is more trouble than it's worth at the moment.

* [market] add markProofAsMissing()

* [clock] speed up waiting for clock in tests

* [validator] mark proofs as missing

* [timer] fix error on node shutdown

* [cli] handle --persistence and --validator separately

* [market] allow retrieval of proof timeout value

* [validator] do not subscribe to SlotFreed events

Freed slots are already handled in
removeSlotsThatHaveEnded(), and onSlotsFreed()
interfered with its iterator.

* [validator] Start validation at the start of a new period

To decrease the likelihood that we hit the validation timeout.

* [validator] do not mark proofs as missing after timeout

* [market] check whether proof can be marked as missing

* [validator] simplify validation

Simulate a transaction to mark proof as missing, instead
of trying to keep track of all the conditions that may
lead to a proof being marked as missing.

* [build] use nim-ethers PR #40

Uses "pending" blocktag instead of "latest" blocktag
for better simulation of transactions before sending
them.

https://github.com/status-im/nim-ethers/pull/40

* [integration] integration test for validator

* [validator] monitor a maximum number of slots

Adds cli parameter --validator-max-slots.

* [market] fix missing collateral argument

After rebasing, add the new argument to fillSlot calls.

* [build] update to nim-ethers 0.2.5

* [validator] use Set instead of Table to keep track of slots

* [validator] add logging

* [validator] add test for slot failure

* [market] use "pending" blocktag to use more up to date block time

* [contracts] remove unused import

* [validator] fix: wait until after period ends

The smart contract checks that 'end < block.timestamp',
so we need to wait until the block timestamp is greater
than the period end.

[marketplace] Add Reservations Module (#340)
* [marketplace] reservations module

- add de/serialization for Availability
- add markUsed/markUnused in persisted availability
- add query for unused
- add reserve/release
- reservation module tests
- split ContractInteractions into client contracts and host contracts
- remove reservations start/stop as the repo start/stop is being managed by the node
- remove dedicated reservations metadata store and use the metadata store from the repo instead
- Split ContractInteractions into:
  - ClientInteractions (with purchasing)
  - HostInteractions (with sales and proving)
- compilation fix for nim 1.2

[repostore] fix started flag, add tests

[marketplace] persist slot index
For loading the sales state from chain, the slot index was not previously persisted in the contract. Will retrieve the slot index from the contract when the sales state is loaded.

* Revert repostore changes

In favour of separate PR https://github.com/status-im/nim-codex/pull/374.

* remove warnings

* clean up

* tests: stop repostore during teardown

* change constructor type identifier

Change Contracts constructor to accept Contracts type instead of ContractInteractions.

* change constructor return type to Result instead of Option

* fix and split interactions tests

* clean up, fix tests

* find availability by slot id

* remove duplication in host/client interactions

* add test for finding availability by slotId

* log instead of raiseAssert when failed to mark availability as unused

* move to SaleErrored state instead of raiseAssert

* remove unneeded reverse

It appears that order is not preserved in the repostore, so reversing does not have the intended effect here.

* update open api spec for potential rest endpoint errors

* move functions about available bytes to repostore

* WIP: reserve and release availabilities as needed

WIP: not tested yet

Availabilities are marked as used when matched (just before downloading starts) so that future matching logic does not match an availability currently in use.

As the download progresses, batches of blocks are written to disk, and the equivalent bytes are released from the reservation module. The size of the availability is reduced as well.

During a reserve or release operation, availability updates occur after the repo is manipulated. If the availability update operation fails, the reserve or release is rolled back to maintain correct accounting of bytes.

Finally, once download completes, or if an error occurs, the availability is marked as unused so future matching can occur.

* delete availability when all bytes released

* fix tests + cleanup

* remove availability from SalesContext callbacks

Availability is no longer used past the SaleDownloading state in the state machine. Cleanup of Availability (marking unused) is handled directly in the SaleDownloading state, and no longer in SaleErrored or SaleFinished. Likewise, Availabilities shouldn’t need to be handled on node restart.

Additionally, Availability was being passed in SalesContext callbacks, and now that Availability is only used temporarily in the SaleDownloading state, Availability is contextually irrelevant to the callbacks, except in OnStore possibly, though it was not being consumed.

* test clean up

* - remove availability from callbacks and constructors from previous commit that needed to be removed (oopsie)
- fix integration test that checks availabilities
  - there was a bug fixed that crashed the node due to a missing `return success` in onStore
  - the test was fixed by ensuring that availabilities are remaining on the node, and the size has been reduced
- change Availability back to non-ref object and constructor back to init
- add trace logging of all state transitions in state machine
- add generally useful trace logging

* fixes after rebase

1. Fix onProve callbacks
2. Use Slot type instead of tuple for retrieving active slot.
3. Bump codex-contracts-eth that exposes getActivceSlot call.

* swap contracts branch to not support slot collateral

Slot collateral changes in the contracts require further changes in the client code, so we’ll skip those changes for now and add in a separate commit.

* modify Interactions and Deployment constructors

- `HostInteractions` and `ClientInteractions` constructors were simplified to take a contract address and no overloads
- `Interactions` prepared simplified so there are no overloads
- `Deployment` constructor updated so that it takes an optional string parameter, instead `Option[string]`

* Move `batchProc` declaration

`batchProc` needs to be consumed by both `node` and `salescontext`, and they can’t reference each other as it creates a circular dependency.

* [reservations] rename `available` to `hasAvailable`

* [reservations] default error message to inner error msg

* add SaleIngored state

When a storage request is handled but the request does match availabilities, the sales agent machine is sent to the SaleIgnored state. In addition, the agent is constructed in a way that if the request is ignored, the sales agent is removed from the list of active agents being tracked in the sales module.
