watcher.state: Use strings, not objects

Until now the state class would receive instances as objects
(ganeti.watcher.Instance), but this is not necessary. By using strings
the interface is simplified.

This patch also simplifies some code accessing the internal structures,...

Change OpClusterVerifyDisks to per-group opcodes

Until now verifying disks, which is also used by the watcher,
would lock all nodes and instances. With this patch the opcode
is changed to operate on per nodegroup, requiring fewer locks.

Both “gnt-cluster” and “ganeti-watcher” are changed for the...
