Summary

• hermes started with two chain configuration takes 2-3 minutes to filter through all the hub channels and figure out it needs to handle only one. This needs optimization. (High startup time for hermes #998 )
• hermes gives a lot of spurious error warn level logs about non-IBC events, these should be lowered to trace or removed (Spurious error logs  #991)
• hermes query clients returns only the client IDs in lexicographic order which is not helpful (especially on the hub with hundreds of clients) . Also one has to query individual clients to determine the counterparty chain. We should allow filtering with a remote chain ID; if one is not specified display and order by chain ID (Include chain-id in hermes query clients output  #992)
