Ubotu failover setup

I had discussed a similar solution a while ago when we lost ubotu to
something or other.  It wasn't nearly this detailed, but we realized that we
needed something automatic in place.

The only issue that I can see with your plan is that when ubotu regains its
connection after a netsplit or similar connectivity disruption, it does not
reconnect to its channels a timely fashion, or at all.  So either we need to
fix the root cause of that, or have the backup bots failover on a channel by
channel basis.
