New Module: "BePrepared" - Distributed task failover.

[ChillFish8]

BePrepared should aim to act like a distributed write-ahead log essentially, the idea being that one node can begin a 'transaction' or operation, selecting 2 other available nodes to be the backup nodes as such.
In the event of the primary node/leader going down, another node which was selected will take over the operation.

Needs more thinking about a suitable solution to this problem. Should this be backed by something like a multi-raft solution, or is a custom state machine better?
