I'm working on trying to understand this to see what common code we can
use between this and ctdb/tests/simple/scripts/local_daemons.bash.  I
figure we should be able to factor out all of the CTDB provisioning
code...

In the existing CTDB local daemon testing code we start up 3 daemons and
run CTDB tests against them.

I'll have a play and see what I can figure out...

peace & happiness,
martin
