[glusterd/snapshot] snapshot create force option

Implement force option in snapshot create i.e

1) Creation of snapshot fails if the original volume
bricks are down
2) With a force option creation of snapshot will continue
even if the original volume bricks are down.

This was the fix for bugs 1089527 and 1083502
