Remove WARN logging level for missing chain id in configuration file

[karzak]

Crate

relayer

Summary

When running hermes, I don't see why missing chain for id ({}) in configuration file should be log_level = WARN.

Problem Definition

In practice, relayers know which chains they are trying to relay between, and this message becomes very noisy/redundant. If you are relaying between chains with lower traffic, 90% of logs are just that warning, making it difficult to parse when actual errors/warnings occur.

Proposal

I wouldn't log anything for this event because things happening on chains that are not in config.toml are irrelevant to the relayer operator. I could also see making it log_level = DEBUG.

Hi guys, I wish I had thought of the simple solution myself. This will definitely make logs easier to read.
