Teleporter Renaming

[martineckardt]

Teleporter is getting renamed to Avalanche Interchain Messaging. Therefore, I propose to reorganize the command tree:

Since the new names are pretty long, I recommend offering the full name and a shorthand alias (e.g. icm and interchain-messaging).

• avalanche
  • icm / interchain-messaging
  • deploy
  • relayer
    • start
    • stop
    • logs
  • track (prev. msg)
  • ictt / interchain-token-transfer
  • deploy

we already have interchain command group, with subcmd tokenTransferrer, why not

- `avalanche`
  - `icm` / `interchain messaging`
    - `deploy`
    - `track` (prev. msg)
  - `ictt` / `interchain tokenTransferrer`
    - `deploy`
  - `interchain relayer`
    - `start`
    - `stop`
    - `logs`

Notice that I'm proposing tokenTransferrer as it is already there and the name better points to its function (transfer points to a standard funds transfer at first sight). But no opposite to using transfer if devrel prefers so.

Also notice that it is using camel case convention (the currently one used at CLI). This is currently a point of discussion for the command tree.
