At the moment, there are no metrics to help validators analyze the connection to the remote signers / KMS.

As a first step, I would suggest adding the following metrics to the node:

• remote_signer_request_count
• remote_signer_request_failed
• remote_signer_request_roundtrip
• remote_signer_ping_count
• remote_signer_ping_failed
• remote_signer_ping_roundtrip

As a follow up of this issue (matching error codes) #3752 , more instrumentation could be added wrt the specific error codes, etc.
