glusterd/snapshot: Fail snap create even if one brick is down.
In a n-way replication, where n>=3 fail snapshot,
even if one brick is down.
Also check for glusterd quorum, irrespective of the force option
Modified testcase tests/bugs/snapshot/bug-1090042.t because
it tested the successful creation of snapshot with force
command.
