Log packet type and payload on success

[ebuchman]

Crate

relayer-cli

Summary

Include the packet type and the payload in the hermes log output to facilitate debugging. Eg. for ICS20 packets, operators can see the sender, receiver, and amount

Problem Definition

On success Hermes logs look something like:

May 28 08:27:51.216 DEBUG ibc_relayer::foreign_client: [cosmoshub-4 -> informal-testnet-1:07-tendermint-1] MsgUpdateAnyClient for target height 4-6378999 and trusted height 4-6356135

Might be nice if there was a bit more data on the actual packet that got relayed.

This was something that came up a few times during my demo that it would have been nice to see which address the packet was relayed for.

Obviously not a high priority, just a nice to have.
