Implement resilient transport channels

It would be extremely useful if the c2 client had the capability to implement a fail-over transport mechanism. Ideally, in the event of an extremely long timeout where the client never receives a response from the server (e.g. 2 weeks), it should attempt to change over to attempt to use a different transport channel for communication.

The fail-over channel should be stored in memory in an encrypted or encoded fashion that would only ever be used in the event it is required. It may be beneficial to either encode/encrypt, or clear from memory entirely the now unusable communication channel.
