Relayer CLIs for connection messages

[ancazamfir]

Summary

We should be able to send transactions from the relayer CLI for all IBC connection messages. Light client requests should be made to fetch the headers at required heights, chains should be queried for connection and consensus state with proofs, etc.

Proposal

The following CLIs should be implemented by the relayer:

1. relayer tx raw conn-init <to-chain-A> <remote-chain-B> <client-B-on-A> <client-A-on-B> <conn-id-on-A> <conn-id-on-B> (Implement relayer CLI for MsgConnectionOpenInit #206)

   • sends a MsgConnectionOpenInit to to-chain-A with

   connection_id = conn-id-on-A,
   client_id = client-B-on-A,
   counterparty_connection_id = conn-id-on-B,
   counterparty_client_id = client-A-on-B,
   counterparty_commitment_prefix = get_store_prefix(remote-chain-B),
   signer = get_account(to-chain-A),
   

2. ConnOpenTry: Relayer CLI for MsgConnectionOpenTry #358

3. ConnOpenAck: Relayer CLI for MsgConnectionOpenAck #359

4. ConnOpenConfirm: Relayer CLI for MsgConnectionOpenConfirm #360
