Follow up on proto changes after deduplication fixes

[ancazamfir]

Summary

As a follow-up on informalsystems/hermes#284 (and PR informalsystems/hermes#292), there are some leftover problems to solve?

• MsgConnectionOpenAck includes a new field counterparty_connection_id. Some minimal changes were done to handle this as part of Tendermint protobuf dependency for IBC proto informalsystems/hermes#292 but tests need to be added. Also, the test infrastructure here is very hard to follow, maybe some cleanup would be nice
• MsgConnectionOpenInit includes a new version field. Some minimal changes were done but tests need to be updated. Also the whole connection versioning will probably need to be inspected to make sure it confirms with latest ICS. (fixed in Migration to stargate 5 ibc-proto-rs#12)
• MsgConnectionOpenTry includes a new previous_connection_id field. This requires updates to the message handler's validation logic and new tests. (fixed in Migration to stargate 5 ibc-proto-rs#12)
• tendermint ClientState has new fields proof_specs (will be handled in Follow-up to migration work informalsystems/hermes#469) and upgrade_path that are currently ignored (will be handled and tested in Relayer CLI for client upgrade message informalsystems/hermes#357).
• A new MsgUpgradeClient msg is defined and needs to be implemented (Update sp-io requirement from 12.0.0 to 13.0.0 in /ci/no-std-check #357)
  [ ] MsgUpdateClient has a new field consensus_params that needs to be consumed by current code base.
  removed in cosmos v0.40.0-rc5
• query commands fail for client, type_urls need to be updated, fixed in Fix Client queries after last protobuf updates informalsystems/hermes#309
• Introduce a newtype for versions (fixed in Migration to stargate 5 ibc-proto-rs#12)
