We have been seeing some port conflicts like:
```
[2023-08-15T00:31:47.625Z] Geth 0 failed to start
```
```
$ tail -n1 local-testnet-mainnet/logs/geth.?.txt
==> local-testnet-mainnet/logs/geth.0.txt <==
Fatal: Error starting protocol stack: listen tcp :6801: bind: address already in use
==> local-testnet-mainnet/logs/geth.1.txt <==
Fatal: Error starting protocol stack: listen tcp :6806: bind: address already in use
==> local-testnet-mainnet/logs/geth.2.txt <==
Fatal: Error starting protocol stack: listen tcp :6811: bind: address already in use
```
In order to debug this we'll need to add printing of some extra info
into `unstable` so feature branches include it.

Signed-off-by: Jakub Sokołowski <jakub@status.im>
* 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.
* Local sim impovements
* Added support for running Capella and EIP-4844 simulations
by downloading the correct version of Geth.
* Added support for using Nimbus remote signer and Web3Signer.
Use 2 out of 3 threshold signing configuration in the mainnet
configuration and regular remote signing in the minimal one.
* The local testnet simulation can now use a payload builder.
This is currently not activated in CI due to lack of automated
procedures for installing third-party relays or builders.
You are adviced to use mergemock for now, but for most realistic
results, we can create a simple builder based on the nimbus-eth1
codebase that will be able to propose transactions from the regular
network mempool.
* Start the simulation from a merged state. This would allow us
to start removing pre-merge functionality such as the gossip
subsciption logic. The commit also removes the merge-forcing
hack installed after the TTD removal.
* Consolidate all the tools used in the local simulation into a
single `ncli_testnet` binary.
* Working Makefile targets for Capella devnet2
make capella-devnet-2
make clean-capella-devnet-2
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.
Local testnet simulation currently waits 5 seconds when starting each
individual Geth instance. Waiting a shorter amount saves almost a minute
per minimum + mainnet CI finalization job.
Measured startup times per Geth: Linux ~100ms, macOS Intel ~300ms.
The ports for the concurrently executing REST and Minimal testnet clash,
leading to some CI failures since #3827 introduced further concurrency.
Adjusting the ports to be distinct across various tests should fix this.
* Add support for launching Geth and Nimbus-eth1 nodes in launch_local_simulation
* Prevent undefined variables errors when Nimbus and Geth are not launched
