Make relayer logs accessible through command and format

[martineckardt]

Currently users can only access relayer logs by printing out the log file at ~/.avalanche-cli/runs/awm-relayer.log.

Could we implement a avalanche teleporter relayer logs command that not only print it out, but also formats the json?

So this here:
