glusterd: Don't allow remove brick start/commit if glusterd is down of the host of the brick
Backport of http://review.gluster.org/#/c/11726/
remove brick stage blindly starts the remove brick operation even if the
glusterd instance of the node hosting the brick is down. Operationally its
incorrect and this could result into a inconsistent rebalance status across all
the nodes as the originator of this command will always have the rebalance
status to 'DEFRAG_NOT_STARTED', however when the glusterd instance on the other
nodes comes up, will trigger rebalance and make the status to completed once the
rebalance is finished.
This patch fixes two things:
1. Add a validation in remove brick to check whether all the peers hosting the
bricks to be removed are up.
2. Don't copy volinfo->rebal.dict from stale volinfo during restore as this
might end up in a incosistent node_state.info file resulting into volume status
command failure.
