Fix the corrupted database state on Pyrmont nodes; Add mainnet genesis (#2056)
* Handle some web3 timeouts better

* Add support for developer .env files

* Eth1 improvements; Mainnet genesis state

Notable changes:

* The deposits table have been removed from the database. The client
  will no longer process all deposits on start-up.

* The network metadata now includes a "state snapshot" of the deposit
  contract. This allows the client to skip syncing deposits made prior
  to the snapshot (i.e. genesis). Suitable metadata added for Pyrmont
  and Mainnet.

* The Eth1 monitor won't be started unless there are validators attached
  to the node.

* The genesis detection code is now optional and disabled by default

* Bugfix: The client should not produce blocks that will fail validation
  when it hasn't downloaded the latest deposits yet

* Bugfix: Work around the database corruption affecting Pyrmont nodes

* Remove metadata for Toledo and Medalla

misc fixes (#2027)
* log when database is loading (to avoid confusion)
* generate network keys later during startup
* fix quarantine not scheduling chain of parents for download and
increase size to one epoch

Jacek Sieka fc7885b27e Store block summary in database
This introcudes a cache for block summaries, useful for instantiating
the block dag on startup, bringing medalla startup times down from
minutes to seconds.

This is something of a temporary band-aid that would be obsoleted by a
finalized block store.

tone down validator exit logging (#1939)
Validators exiting is normal, no need to scream about it

* avoid reallocating seq on big exit queue
* avoid fetching state cache when updating head (it's rarely needed)

misc memory and perf fixes (#1899)
* misc memory and perf fixes

* use EpochRef for attestation aggregation
* compress effective balances in memory (medalla unfinalized: 4gb ->
1gb)
* avoid hitting db when rewinding to head or clearance state
* avoid hitting db when blocks can be applied to in-memory state -
speeds up startup considerably
* avoid storing epochref in fork choice
* simplify and speed up beacon block creation flow - avoids state reload
thanks to head rewind optimization
* iterator-based committee and attestation participation help avoid lots
of small memory allocations throughout epoch transition (40% speedup on
epoch processing, for example during startup)

* add constant for threshold

fix db growth on attestation processing (#1860)
It turns out that we often save lots of states in the database that are
the result of empty slot processing only - here, we make sure to only
save a state if a block follows - this fixes several issues:

* empty slot states are not always pruned leading to state database size
explosion
* storing states is (very) slow which slows down processing in general,
so we should only do it when it's likely to be useful
* attestation processing doesn't get stuck on saving random states that
won't appear in the chain history

* make epochRef available from within onBlockAdded callback
* integrate getEpochInfo into block resolution and epoch ref logic such
that epochrefs are created when blocks are added to pool or lazily when
needed by a getEpochRef
* fill state cache better from EpochRef, speeding up replay and
validation
* store epochRef in specific blocks to make them easier to find and
reuse
* fix database corruption when state is saved while replaying quarantine
* replay slots fully from block pool before processing state
* compare bls values more smartly
* store epoch state without block applied in database - it's recommended
to resync the node!

this branch will drastically speed up processing in times of long
non-finality, as well as cut memory usage by 10x during the recent
medalla madness.

fix invalid state root being written to database (#1493)
* fix invalid state root being written to database

When rewinding state data, the wrong block reference would be used when
saving the state root - this would cause state loading to fail by
loading a different state than expected, preventing blocks to be
applied.

* refactor state loading and saving to consistently use and set
StateData block
* avoid rollback when state is missing from database (as opposed to
being partially overwritten and therefore in need of rollback)
* don't store state roots for empty slots - previously, these were used
as a cache to avoid recalculating them in state transition, but this has
been superceded by hash tree root caching
* don't attempt loading states / state roots for non-epoch slots, these
are not saved to the database
* simplify rewinder and clean up funcitions after caches have been
reworked
* fix chaindag logscope
* add database reload metric
* re-enable clearance epoch tests
