Implement IBC transactions

[jackzampolin]

Each individual IBC transaction should be able to be run by the relayer individually as well as in logical groupings (channel, connection). These primitives can then be combined in strategies.go in a number of ways.

The following are the necessary txs:

• [x] client [src-chain-id] [dst-chain-id] [client-id]
• [x] update-client [src-chain-id] [dst-chain-id] [client-id]
• [x] clients [src-chain-id] [dst-chain-id] [src-client-id] [dst-client-id]
• [x] connection [src-chain-id] [dst-chain-id] [src-client-id] [dst-client-id] [src-connection-id] [dst-connection-id]
• [x] connection-step [src-chain-id] [dst-chain-id] [src-client-id] [dst-client-id] [src-connection-id] [dst-connection-id]
• [x] channel [src-chain-id] [dst-chain-id] [src-connection-id] [dst-connection-id] [src-channel-id] [dst-channel-id] [src-port-id] [dst-port-id]
  • [x] channel-step [src-chain-id] [dst-chain-id] [src-connection-id] [dst-connection-id] [src-channel-id] [dst-channel-id] [src-port-id] [dst-port-id]
• [ ] flush-chan [src-chain-id] [dst-chain-id] [src-channel-id] [src-port-id]
• [x] raw
  • [x] conn-init
  • [x] conn-try
  • [x] conn-ack
  • [x] conn-confirm
  • [x] chan-init
  • [x] chan-try
  • [x] chan-ack
  • [x] chan-confirm
  • [x] chan-close-init
  • [x] chan-close-confirm
