* implement a logging proxy
The logging proxy:
- prevents the need to import chronicles (as well as export except toJson),
- prevents the need to override `writeValue` or use or import nim-json-seralization elsewhere in the codebase, allowing for sole use of utils/json for de/serialization,
- and handles json formatting correctly in chronicles json sinks
* Rename logging -> logutils to avoid ambiguity with common names
* clean up
* add setProperty for JsonRecord, remove nim-json-serialization conflict
* Allow specifying textlines and json format separately
Not specifying a LogFormat will apply the formatting to both textlines and json sinks.
Specifying a LogFormat will apply the formatting to only that sink.
* remove unneeded usages of std/json
We only need to import utils/json instead of std/json
* move serialization from rest/json to utils/json so it can be shared
* fix NoColors ambiguity
Was causing unit tests to fail on Windows.
* Remove nre usage to fix Windows error
Windows was erroring with `could not load: pcre64.dll`. Instead of fixing that error, remove the pcre usage :)
* Add logutils module doc
* Shorten logutils.formatIt for `NBytes`
Both json and textlines formatIt were not needed, and could be combined into one formatIt
* remove debug integration test config
debug output and logformat of json for integration test logs
* Use ## module doc to support docgen
* temporarily remove failing integration test
Temporarily removing this test for now as it occasionally fails on macos/linux. This test has been completely refactored in PR #607 in which it will be retintroduced.
* skip instead of comment out
* Workaround for Hardhat timestamp bug
Likely due to a Hardhat bug in which the callbacks for subscription events are called and awaited before updating its local understanding of the last block time, Hardhat will report a block time in the `newHeads` event that is generally 1 second before the time reported from `getLatestBlock.timestamp`. This was causing issues with the OnChainClock's offset and therefore the `now()` used by the `OnChainClock` would sometimes be off by a second (or more), causing tests to fail.
This commit introduce a `codex_use_hardhat` compilation flag, that when set, will always get the latest block timestamp from Hardhat via the `getLatestBlock.timestamp` RPC call for `OnChainClock.now` calls. Otherwise, the last block timestamp reported in the `newHeads` event will be used.
Update the docker dist tests compilation flag for simulated proof failures (it was not correct), and explicitly add the `codex_use_hardhat=false` for clarity.
* enable simulated proof failures for coverage

* Add get active slot /slots/{slotId} to REST api, use utils/json
- Add endpoint /slots/{slotId} to get an active SalesAgent from the Sales module. Used in integration tests to test when a sale has reached a certain state. Those integration test changes will be included in a larger PR, coming later.
- Add OpenAPI changes for new endpoint and associated components
- Use utils/json instead of nim-json-serialization. Required exemption of imports from several packages that export nim-json-serialization by default.
* Only except `toJson` from import/export of chronicles
In proving.onCancelled, the `waitFor state.loop.cancelAndWait()` was never completing. Turns out this was not needed, because when changing states, the current state's run is cancelled, which automatically cancels the state prove loop, because it is a child of proving.run. Therefore, the logic to cancelAndWait the prove loop was removed as it was not needed.

## Problem
When Availabilities are created, the amount of bytes in the Availability are reserved in the repo, so those bytes on disk cannot be written to otherwise. When a request for storage is received by a node, if a previously created Availability is matched, an attempt will be made to fill a slot in the request (more accurately, the request's slots are added to the SlotQueue, and eventually those slots will be processed). During download, bytes that were reserved for the Availability were released (as they were written to disk). To prevent more bytes from being released than were reserved in the Availability, the Availability was marked as used during the download, so that no other requests would match the Availability, and therefore no new downloads (and byte releases) would begin. The unfortunate downside to this, is that the number of Availabilities a node has determines the download concurrency capacity. If, for example, a node creates a single Availability that covers all available disk space the operator is willing to use, that single Availability would mean that only one download could occur at a time, meaning the node could potentially miss out on storage opportunities.
## Solution
To alleviate the concurrency issue, each time a slot is processed, a Reservation is created, which takes size (aka reserved bytes) away from the Availability and stores them in the Reservation object. This can be done as many times as needed as long as there are enough bytes remaining in the Availability. Therefore, concurrent downloads are no longer limited by the number of Availabilities. Instead, they would more likely be limited to the SlotQueue's `maxWorkers`.
From a database design perspective, an Availability has zero or more Reservations.
Reservations are persisted in the RepoStore's metadata, along with Availabilities. The metadata store key path for Reservations is ` meta / sales / reservations / <availabilityId> / <reservationId>`, while Availabilities are stored one level up, eg `meta / sales / reservations / <availabilityId> `, allowing all Reservations for an Availability to be queried (this is not currently needed, but may be useful when work to restore Availability size is implemented, more on this later).
### Lifecycle
When a reservation is created, its size is deducted from the Availability, and when a reservation is deleted, any remaining size (bytes not written to disk) is returned to the Availability. If the request finishes, is cancelled (expired), or an error occurs, the Reservation is deleted (and any undownloaded bytes returned to the Availability). In addition, when the Sales module starts, any Reservations that are not actively being used in a filled slot, are deleted.
Having a Reservation persisted until after a storage request is completed, will allow for the originally set Availability size to be reclaimed once a request contract has been completed. This is a feature that is yet to be implemented, however the work in this PR is a step in the direction towards enabling this.
### Unknowns
Reservation size is determined by the `StorageAsk.slotSize`. If during download, more bytes than `slotSize` are attempted to be downloaded than this, then the Reservation update will fail, and the state machine will move to a `SaleErrored` state, deleting the Reservation. This will likely prevent the slot from being filled.
