std/osproc,
first batch of work towards the VC/BN split: - 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

REST API client, JSON-RPC cleanups (#2756) This refactoring puts the JSON-RPC and REST APIs on more equal footing by renaming and moving things around, creating a separation between client and server, and documenting what they are - the aim is to have a simple-to-use base to start from when developing API clients, as well as make it easier to navigate the code when looking for the legacy JSON-RPC interface vs the new REST API. * move REST client, serialization and supporting types to spec/eth2_apis * REST stuff now starts with `rest_`, JSON-RPC stuff starts with `rpc_`, more or less * simplify imports such that there's a simple module to import for both server and client * map REST type and proc names to yaml spec more closely - in particular, reuse operation and type names in `rest_types` to make comparisons against spec more easy * cleaner separation between client and server modules - modules common between server and client such as `rest_types` and serialization move to the spec folder - this allows the client to be built with less knowledge about server internals

Bump modules to take advantage of the new Json format flavors support Since quite a lot of additional procs were now compiled as generics, this lead to compiler bugs that had to be worked-around: * The `Domain` type was renamed to `Eth2Domain` to avoid compilation errors due to conflicts with `nativesockets.Domain`. Similarly, `eth2_network.KeyPair` was renamed to `NetKeyPair`. * A new more robust version of `hexToByteArray` was added to stew

singe validator key cache Instead of keeping a validator key list per EpochRef, this PR introduces a single shared validator key list in ChainDAG, and cleans up some other ChainDAG and key-related issues. The PR does not introduce the validator key list in the state transition - this is because we batch-check all signatures before entering the spec code, thus the spec code never hits the cache. A future refactor should _probably_ remove the threadvar altogether. There's a few other small fixes in here that make the flow easier to read: * fix `var ChainDAGRef` -> `ChainDAGRef` * fix `var QuarantineRef` -> `QuarantineRef` * consistent `dag` variable name * avoid using threadvar pubkey cache in most cases * better error messages in batch signature checking
