Fix a potential segfault and various potential stalls (#4003) 
* Fixes a segfault during block production when the Keymanager API
  is disabled. The Keymanager is now disabled on half of the local
  testnet nodes to catch such problems in the future.

* Fixes multiple potential stalls from REST requests being done
  without a timeout. From practice, we know that such requests
  can hang forever if not cancelled with a timeout. At best,
  this would be a resource leak, at worst, it may lead to a
  full stall of the client and missed validator duties.

* Changes some Options usages to Opt (for easier use of valueOr)

time: spring cleaning (#3262) 
Time in the beacon chain is expressed relative to the genesis time -
this PR creates a `beacon_time` module that collects helpers and
utilities for dealing the time units - the new module does not deal with
actual wall time (that's remains in `beacon_clock`).

Collecting the time related stuff in one place makes it easier to find,
avoids some circular imports and allows more easily identifying the code
actually needs wall time to operate.

* move genesis-time-related functionality into `spec/beacon_time`
* avoid using `chronos.Duration` for time differences - it does not
support negative values (such as when something happens earlier than it
should)
* saturate conversions between `FAR_FUTURE_XXX`, so as to avoid
overflows
* fix delay reporting in validator client so it uses the expected
deadline of the slot, not "closest wall slot"
* simplify looping over the slots of an epoch
* `compute_start_slot_at_epoch` -> `start_slot`
* `compute_epoch_at_slot` -> `epoch`

A follow-up PR will (likely) introduce saturating arithmetic for the
time units - this is merely code moves, renames and fixing of small
bugs.

Logging and startup improvements (#3038) 
* Logging and startup improvements

Color support for released binaries!

* detect tty:s vs redirected logs and log accordingly
* add option to disable log colors at runtime
* simplify several "common" logs, showing the most important information
earlier and more clearly
* remove line numbers / file information / tid - these take up space and
are of little use to end users
  * still enabled in debug builds and tools

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

Perform attestation check before broadcast (#2550) 
Currently, we have a bit of a convoluted flow where when sending
attestations, we start broadcasting them over gossip then pass them to
the attestation validation to include them in the local attestation pool
- it should be the other way around: we should be checking attestations
_before_ gossipping them - this serves as an additional safety net to
ensure that we don't publish junk - this becomes more important when
publishing attestations from the API.

Also, the REST API was performing its own validation meaning
attestations coming from REST would be validated twice - finally, the
JSON RPC wasn't pre-validating and would happily broadcast invalid
attestations.

* Unified attestation production pipeline with the same flow for gossip,
locally and API-produced attestations: all are now validated and entered
into the pool, then broadcast/republished
* Refactor subnet handling with specific SubnetId alias, streamlining
where subnets are computed, avoiding the need to pass around the number
of active validators
* Move some of the subnet handling code to eth2_network
* Use BitArray throughout for subnet handling

avoid some slashing protection queries (#2528) 
This PR reduces the number of database queries for slashing protection
from 5 reads and 1 write to 2 reads and 1 write in the optimistic case.

In the process, it removes user-level support for writing the database
in the version 1 format in order to simplify the code flow, and prevent
code rot. In particular, the v1 format was not covered by any unit tests
and has no advantages over v2. The concrete code to read and write it
remains for now, in particular to support upgrades from v1 to v2.

The branch also removes the use of concepts which doesn't work with
checked exceptions - in particular, this highlights code that both
raises exceptions and returns error codes, which could be cleaned up in
the future.

* Cache internal validator ID
* Rely on unique index to check for trivial duplicate votes
* Combine two surround vote queries into one
* Combine API for checking and registering slashing into single function

The slashing DB is normally not a bottleneck, but may become one with
high attached validator counts.

fix subnet calculation in RPC and insert broadcast attestations into node's pool (#2207) 
* fix subnet calculation in RPC and insert broadcast attestations into node's pool

* unify codepaths to ensure only mostly-checked-to-be-valid attestations enter the pool, even from node's own broadcasts

* update attestation pool tests for new validateAttestation param

make subnet cycling more robust; use one stability subnet/validator; explicitly represent gossip enabled/disabled (#2201) 
* make subnet cycling more robust; use one stability subnet/validator; explicitly represent gossip enabled/disabled

* fix asymmetry in _snappy being used for subscriptions but not unsubscriptions

* remove redundant comment

* minimal RPC and VC support for infoming BN of subnets

* create and verify slot signatures in RPC interface and VC

* loosen old slot check

* because Slot + uint64 works but uint64 + Slot doesn't

* document assumptions for head state use; don't clear stability subnets; guard against VC not having checked an epoch ahead, fixing a crash; clarify unsigned comparison

* revert unsub fix
