When accessing DB in `readOnly` mode that does not already have latest
schema, initial writes trigger `attempt to write a readonly database`.
Avoid that by only writing schema when DB is not `readOnly`, and provide
data from legacy tables if such are present.
* Refactor block/blobs types
Use type system to enforce invariant that a pre-4844 block cannot have
a sidecar.

When running `nimbus_light_client`, we persist the latest header from
`LightClientStore.finalized_header` in a database across restarts.
Because the data format is derived from the latest `LightClientStore`,
this could lead to data being persisted in pre-release formats.
To enable us to test later `LightClientStore` versions on devnets,
transition to a `ForkedLightClientStore` internally that is only
migrated to newer forks on-demand (instead of starting at latest).
By enabling the validator monitor, more precise information about the
lifecycle of an attestation is logged at the higher `NOTICE` log level
while current `sent` messages are logged at `INF` instead, since they
are less interesting.
In particular, missed attestations and those that vote for the wrong
head are now detected and logged at NOTICE.
In addition to logging, this feature enables rich metrics around
attestation and sync committee performance - by default, validators are
tracked in aggregate but a detailed mode exists as well
This feature has been available since early Nimbus days, but it has now
been tuned and optimised such that it is safe to enable by default, even
for large setups.
* enable automatic validator monitoring by default
* replace `--validator-monitor-totals` flag with
`--validator-monitor-details` - the detailed mode is disabled by default
* lower "sent" log level to `INF` for several messages - in particular
those that are traced by the validator monitor
This is a retake on #3531 which was later reverted in #3578.
Distinguish between those code locations that need to be updated on each
light client data format change, and those others that should generally
be fine, as long as a valid light client object is processed.
The former are tagged with static assert for `LightClientDataFork.high`.
The latter are changed to `lcDataFork > LightClientDataFork.None` to
indicate that they depend only on presence of any valid object.
Also bundled a few minor cleanups and fixes.
Also add `Forky` type for `LightClientStore` and minor fixes / cleanups.
The light client data structures were changed to accommodate additional
fields in future forks (e.g., to also hold execution data).
There is a minor change to the JSON serialization, where the `header`
properties are now nested inside a `LightClientHeader`.
The SSZ serialization remains compatible.

You'll need to have https://github.com/tmuxinator/tmuxinator installed.
It's available as a regular package in most Linux distributions or through
Nix or Brew on macOS.
This commit also fixes the initial hang in the Eth1 monitor in the "find
TTD block" procedure through a fix to the network metadata files which
hasn't been upstreamed yet.
Other changes:
* Disabled Geth snap sync in the simulation
When all Geth nodes are configured to run with snap sync enabled, they all
start snap sync after the first forkchoiceUpdated which causes the BNs to
skip validator duties because the EL is syncing. The snap sync never completes
due to poor connectivity between the Geth nodes in the simulation.
In a future fork, light client data will be extended with execution info
to support more use cases. To anticipate such an upgrade, introduce
`Forky` and `Forked` types, and ready the database schema.
Because the mapping of sync committee periods to fork versions is not
necessarily unique (fork schedule not in sync with period boundaries),
an additional column is added to `period` -> `LightClientUpdate` table.
* correctly report ignored contributions in metrics
* avoid counting subset contributions in vmon (bring in line with
attestation aggregates)
* avoid signature checks for subset attestations
A being a non-strict subset is a sufficient condition to ignore.
When a database has been pruned, we can still export the non-pruned part
- running the era exported together with pruning allows archiving the
full ethereum history for future reference without wasting space in the
database.
* use logging for reporting era write progress
* less noise when skipping existing files
* load blocks from era store also when working with `ncli_db`
* write to temporary file then rename when era is complete, to reduce
risk of corruption
* also avoids loading the in-progress era file when writing and
reading from the same era folder
Bellatrix and Altair light client data share same body, but have other
fork digests. Validate that the peer's sent fork digest matches the one
that we expect (derived from `attested_header.slot`).
