- better logging & retrying requests on the VC side if the BN fails for some reason
- VC now fetches the attestation duties 1 epoch in advance - in the future it will tell the BN to subscribe to the appropriate attestation topics in advance based on that info
- a bunch of other code cleanup & fixes such as better naming for consoles when using multitail, etc.
reviewed in PR #1184 - proper review of the API & VC are pending
* collect signature production and verificaiton in one place
Signatures are made over data and domain - here we collect all such
activities in one place.

* fix standalone test_block_pool compilation
* add signed block processing in ncli
* reuse cache entry instead of allocating a new one
* allow for small clock disparities when validating blocks

- README: made Witti the documented testnet and added instructions for
getting metrics out of the local node
- moved Prometheus config file generation in its own script
- the static Grafana dashboard definition now covers all nodes, using
a variable; only the remote testnet dashboards need to be dynamically
generated

- each BN gets half of its previous validators as inProcess and the other half goes to the respective VC for that BN - using separate data dirs where the keys are copied
- also removed a few command line options which are no longer necessary
- block proposals originating from a VC are propagated from one BN to the rest properly
- other cleanup & moving code back to since it is no longer used elsewhere

The first offset of an SSZ object should always have a fixed constant
value. Otherwise, some unused bytes may appear between the fixed portion
and the dynamic portion.
Please note that this fix shutds down the minimal forward compatibility
currently supported by the SSZ format (and thus, the expected behavior
must be clarified in the SSZ spec).
* be stricter about SSZ length prefix
* compute zeroHash list at compile time
* remove SSZ schema stuff
* move SSZ navigation to ncli

Fix bug when sync got stuck when some of the workers waiting for failing one.
* Remove debugging comments and imports.
* Remove not used pendingLock.
- we have a new binary which connects via RPC to the respective BN and has an internal clock - waking it up on every slot
- the BN has a new option called --external-validators and currently in order to have the VC binaries to run we need to pass EXTERNAL_VALIDATORS=yes to make
- factored some code out of beacon_node.nim for easier reuse in validator_api.nim and validator_client.nim
- the VC loads its associated private keys from the datadir for its BN
- most of the validator API calls have been implemented as a stub.
- the VC polls its BN at the start of each epoch - getting a list of all active validators for the current epoch - and then continues to request blocks and sign them with its appropriate validators when necessary
* in makeBeaconBlock - use rollback instead
* in tests - this helps state_sim give more accurate data and makes it
30% faster
* fix some usages of raw BeaconState
* update more spec refs in beacon_chain/spec/presets; skip skipped constant sanity checks also from markdown reports' perspectives
* mark skipped as skipped in markdown

* Jenkins: add timeouts to testnet finalisation tests
- add nicer child process management to "launch_local_testnet.sh"
- correct a comment in "start.sh"
* the Jenkins worker's version of "timeout" doesn't support "-v"
* remove near-duplicate code paths: process_slot(), process_slots(), and state_transition() for BeaconState are now wrappers around the HashedBeaconState versions
* convert tests/test_state_transition.nim to use HashedBeaconState
* convert mocking infrastructure and spec_block/epoch_processing tests to use HashedBeaconBlock, and remove thus unused process_slot*(state: var BeaconState)
* ssz: move ref support outside
Instead of allocating ref's inside SSZ, move it to separate helper:
* makes `ref` allocations explicit
* less magic inside SSZ
* `ref` in nim generally means reference whereas SSZ was loading as
value - if a type indeed used references it would get copies instead of
references to a single value on roundtrip which is unexpected
TODO: EF tests would benefit from some refactoring since they all do the
same thing practically..

In BlockPool, we keep the head state around, so it's trivial to restore
the temporary state there and keep going as if nothing happened.
This solves 3 problems:
* stack space - the state copy on mainnet is huge
* GC scanning - using stack space for state slows down the GC
significantly
* reckless copying - the copy itself takes a long time
In state_sim, we'll do the same and allocate on heap - this helps a
little with GC - without it, the collection of the temporary strings
created with `toHex` while printing the json dominates the trace.

The number of user nodes is now specified with `USER_NODES`.
To make the instructions more stable, the "numeric id" of the user
nodes will be starting from 0 (so you can always use `run_node.sh 0`
to start a user node).
If you specify a node index above the total number of nodes, you'll
launch a node without any validators attached (this is useful for
testing the sync for example).
When the connect_to_testnet script is invoked it will first verify that
the genesis file of the testnet hasn't changed. If it has changed, any
previously created database associated with the testnet will be erased.
To facilitate this, the genesis file of each network is written to the
data folder of the beacon node. The beacon node will refuse to start if
it detects a discrepancy between the data folder and any state snapshot
specified on the command-line.
Since the testnet sharing spec requires us to use SSZ snapshots, the Json
support is now phased out. To help with the transition and to preserve the
functionality of the multinet scripts, the beacon node now supports a CLI
query command that can extract any data from the genesis state. This is
based on new developments in the SSZ navigators.

Multi-client testing requires more portable formats, and SSZ is
much better specified than our flavour of Json.
Tools like ncli and zcli can be now used to inspect the contents
of the SSZ files.
