Relayer CLI for MsgConnectionOpenAck

[adizere]

Crate

mostly relayer and relayer-cli, but may cross into modules also

Problem Definition

Implement support for the command:

relayer tx raw conn-ack <to-chain-A> <remote-chain-B> <conn-id-on-B>

• sends request to local client for chain-B to retrieve latest header header_B with height hb
• makes the following queries to chain-B at height hb-1:
  - the connection with id conn-id-on-B with proof, stores results in connection and try_proof
  - the state of client with id client-A-on-B and retrieves the height of last consensus state, last_cs_height
  - the consensus state for client with id client-A-on-B and height last_cs_height with proof, consensus_proof
• sends a MsgUpdateState to chain-A with:

        client_id = client-B-on-A, 
        header = header_B, 
        signer = get_account(to-chain-A)

• sends a MsgConnectionOpenAck to chain-B with:

        connection_id = connection.counterparty_connection_id,
        try_proof
        consensus_proof,
        proofs_height = hb,
        consensus_height = last_cs_height,
        version = connection.versions[0]
        signer = get_account(to-chain-A)

Note: get_... are functions that retrieve information from the relayer configuration.
