Add ipc support in --execution-endpoint

[bayardar]

Description

ipc is not currently supported for the --execution-endpoint it would be a great performance improvement for nodes running both execution-client/consensus-client on the same host.

Version

lighthouse v6.0.1 stable

Present Behaviour

When trying to run the client with --execution-endpoint ipc://<PATH_TO_IPC> it errors with :
--execution-endpoint contains an invalid value RedactError("Unable to redact username.")

Expected Behaviour

The client should be able to connect to the execution client over ipc.

Steps to resolve

Implement IPC

Is there any eta if this will be added to future releases? I wish to use ipc running el and cl on the same system.
