remove bundled pyrmont support (#3568)
The `pyrmont` testnet has been discontinued.

For experiments, it's still possible to run pyrmont nodes by passing a
genesis/config, but this PR removes the bundled `--network:pyrmont`
option.

Support for Gnosis Chain (#3415)
* Support for Gnosis Chain

`make gnosis-chain-build` will build the Nimbus gnosis chain binary,
stored in `build/nimbus_beacon_node_for_gnosis_chain`.

`make gnosis-chain` will connect to the network.

Other changes:

* Restore compilation with -d:has_genesis_detection
* Removed Makefile target related to testnet0 and testnet1
* Added more debug logging for failed peer handshakes
* Report misconfigured builds which try to embed network metadata
that is incompatible with the currently selected const preset.
* Don't bundle network metadata in minimal builds, as they are not compatible

wss_sim: state transition simulator (#3309)
It's sometimes useful to simulate what happens when a chain runs from a
given state with a given set of private keys - `wss_sim` allows running
such a simulation.

One use of such a tool is to simulate a weak subjectivity attack,
creating alternative histories of the same chain:

Zahary Karadjov 47f1f7ff1a More efficient reward data persistance; Address review comments
The new format is based on compressed CSV files in two channels:

* Detailed per-epoch data
* Aggregated "daily" summaries

The use of append-only CSV file speeds up significantly the epoch
processing speed during data generation. The use of compression
results in smaller storage requirements overall. The use of the
aggregated files has a very minor cost in both CPU and storage,
but leads to near interactive speed for report generation.

Other changes:

- Implemented support for graceful shut downs to avoid corrupting
  the saved files.

- Fixed a memory leak caused by lacking `StateCache` clean up on each
  iteration.

- Addressed review comments

- Moved the rewards and penalties calculation code in a separate module

Required invasive changes to existing modules:

- The `data` field of the `KeyedBlockRef` type is made public to be used
  by the validator rewards monitor's Chain DAG update procedure.

- The `getForkedBlock` procedure from the `blockchain_dag.nim` module
  is made public to be used by the validator rewards monitor's Chain DAG
  update procedure.

disentangle eth2 types from the ssz library (#2785)
* reorganize ssz dependencies

This PR continues the work in
https://github.com/status-im/nimbus-eth2/pull/2646,
https://github.com/status-im/nimbus-eth2/pull/2779 as well as past
issues with serialization and type, to disentangle SSZ from eth2 and at
the same time simplify imports and exports with a structured approach.

The principal idea here is that when a library wants to introduce SSZ
support, they do so via 3 files:

* `ssz_codecs` which imports and reexports `codecs` - this covers the
basic byte conversions and ensures no overloads get lost
* `xxx_merkleization` imports and exports `merkleization` to specialize
and get access to `hash_tree_root` and friends
* `xxx_ssz_serialization` imports and exports `ssz_serialization` to
specialize ssz for a specific library

Those that need to interact with SSZ always import the `xxx_` versions
of the modules and never `ssz` itself so as to keep imports simple and
safe.

This is similar to how the REST / JSON-RPC serializers are structured in
that someone wanting to serialize spec types to REST-JSON will import
`eth2_rest_serialization` and nothing else.

* split up ssz into a core library that is independendent of eth2 types
* rename `bytes_reader` to `codec` to highlight that it contains coding
and decoding of bytes and native ssz types
* remove tricky List init overload that causes compile issues
* get rid of top-level ssz import
* reenable merkleization tests
* move some "standard" json serializers to spec
* remove `ValidatorIndex` serialization for now
* remove test_ssz_merkleization
* add tests for over/underlong byte sequences
* fix broken seq[byte] test - seq[byte] is not an SSZ type

There are a few things this PR doesn't solve:

* like #2646 this PR is weak on how to handle root and other
dontSerialize fields that "sometimes" should be computed - the same
problem appears in REST / JSON-RPC etc

* Fix a build problem on macOS

* Another way to fix the macOS builds

Implement split preset/config support (#2710)
* Implement split preset/config support

This is the initial bulk refactor to introduce runtime config values in
a number of places, somewhat replacing the existing mechanism of loading
network metadata.

It still needs more work, this is the initial refactor that introduces
runtime configuration in some of the places that need it.

The PR changes the way presets and constants work, to match the spec. In
particular, a "preset" now refers to the compile-time configuration
while a "cfg" or "RuntimeConfig" is the dynamic part.

A single binary can support either mainnet or minimal, but not both.
Support for other presets has been removed completely (can be readded,
in case there's need).

There's a number of outstanding tasks:

* `SECONDS_PER_SLOT` still needs fixing
* loading custom runtime configs needs redoing
* checking constants against YAML file

* yeerongpilly support

`build/nimbus_beacon_node --network=yeerongpilly --discv5:no --log-level=DEBUG`

* load fork epoch from config

* fix fork digest sent in status
* nicer error string for request failures
* fix tools

* one more

* fixup

* fixup

* fixup

* use "standard" network definition folder in local testnet

Files are loaded from their standard locations, including genesis etc,
to conform to the format used in the `eth2-networks` repo.

* fix launch scripts, allow unknown config values

* fix base config of rest test

* cleanups

* bundle mainnet config using common loader
* fix spec links and names
* only include supported preset in binary

* drop yeerongpilly, add altair-devnet-0, support boot_enr.yaml

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
