Add infrastructure for queriying for remote locks.
Current code, when need to ensure that volume is not
active on remote node, it need to try to exclusive
activate volume.
Patch adds simple clvmd command which queries all nodes
for lock for given resource.
The lock type is returned in reply in text.
(But code currently uses CR and EX modes only.)
