This issue is for implementing command replication support for the set command.
The problem is the set command does not have a target. The target is derived
from the operands of the command and the replication framework will not be aware
of the targets. So there is no way for the framework to know where to send the
commands to. So just as deploy command, set also is a special case. It should be
executed only on DAS and once it is done on DAS, the command impl itself should
decide on replication targets and invoke some hidden command in the instances to
do the set there.
Because of this special treatment for set, Bill and Jerome want to be sure that
things will work - just as we did for deployment special case.
