Holesky genesis.ssz file may be unavailable due to quota limits on
`eth-clients/holesky`; do not download it by default during checkout.
Nimbus will download it on first startup from a mirror instead.
The 'vendor/holesky/public-keys/all.txt' file is not used by Nimbus,
but sometimes fails to download due to payment issues in `@eth-clients`.
Skipping the download of that file should reduce that risk.

* bump nbs: Patch libnatpmp.a rule to support llvm-mingw in targets.mk
* bump nbs: Allow passing config to submodule initialization in `update-common`
Add a hint message during git clone to direct the user to install
Git LFS if it is missing. It is required to clone Holesky submodule.

The CI signing node sometimes becomes overloaded, leading to late block.

Especially on the `minimal` preset with short slot timings, this leads
to attestations and sync duties being made for an old head, ultimately:

Looking at `nimbus_signing_node.0.jsonl` shows that the signing node is
very busy. Lowering the validator count should reduce the latency a bit.
Port 9952 sometimes seems blocked, maybe by another Status project
being tested on the same host, or by UPS process, or maybe it needs
SO_REUSEPORT as well?
Switch to 9962 for now to see if that improves things.

I couldn't install those packages with the versions previously stated.
The new versions install successfully,
and `make publish-book` works without errors.
* Add support for using custom remote signers in local sim
Other changes:
* Enable the Nimbus remote signer in the minimal simulation
* Move all log files into the `logs` folder of the simulation
* Create PID files for all processes and use them during the clean-up
phase instead of the previous more fragile methods for killing the
remaining processes.
* Refactor nimbus_signing_node to support Unix signals.
* Fix SN unable to close REST server properly.
* Fix `keys`, `deposit` and `validator_registration` endpoints issues.
Add getValidatorExitSignature() and getDepositMessageSignature() to validator_pool.
* Add /reload endpoint and implementation.
Fix signData to not cancel `timer`.
Fix validator_pool should clear attachedValidators table.
* Diva protocol enhancement implementation.
* Support for driving multiple EL nodes from a single Nimbus BN
Full list of changes:
* Eth1Monitor has been renamed to ELManager to match its current
responsibilities better.
* The ELManager is no longer optional in the code (it won't have
a nil value under any circumstances).
* The support for subscribing for headers was removed as it only
worked with WebSockets and contributed significant complexity
while bringing only a very minor advantage.
* The `--web3-url` parameter has been deprecated in favor of a
new `--el` parameter. The new parameter has a reasonable default
value and supports specifying a different JWT for each connection.
Each connection can also be configured with a different set of
responsibilities (e.g. download deposits, validate blocks and/or
produce blocks). On the command-line, these properties can be
configured through URL properties stored in the #anchor part of
the URL. In TOML files, they come with a very natural syntax
(althrough the URL scheme is also supported).
* The previously scattered EL-related state and logic is now moved
to `eth1_monitor.nim` (this module will be renamed to `el_manager.nim`
in a follow-up commit). State is assigned properly either to the
`ELManager` or the to individual `ELConnection` objects where
appropriate.
The ELManager executes all Engine API requests against all attached
EL nodes, in parallel. It compares their results and if there is a
disagreement regarding the validity of a certain payload, this is
detected and the beacon node is protected from publishing a block
with a potential execution layer consensus bug in it.
The BN provides metrics per EL node for the number of successful or
failed requests for each type Engine API requests. If an EL node
goes offline and connectivity is resoted later, we report the
problem and the remedy in edge-triggered fashion.
* More progress towards implementing Deneb block production in the VC
and comparing the value of blocks produced by the EL and the builder
API.
* Adds a Makefile target for the zhejiang testnet
