Add some code to clvmd to look in the corosync confdb to see what cluster
...
interface it should be using, it can still be overriden with -I.
If corosync isn't running or there is no information then the usual
checking will happen.
This code only builds if corosync is available.

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.)
