Check DRBD status on verify-disks
Enhance `gnt-cluster verify-disks` such that it checks the DRBD statusof all disks. If the status of at least one disk of an instance iseither StandAlone or Diskless, the instance disks are activatedautomatically.

This fixes a 'FIXME' in the xen hypervisor. The instancemigration requires the cluster's name. This should comefrom the RPC call, but so far was hackishly taken fromssconf. Ssconf is intended to be used by scripts only and...

rpc / noded: add hvparams to instance_list call
The 'instance_list' call needs to be extended to accepthvparams. This is one of the few RPCs where it isnecessary, because there is no instance given whosehvparams could be reused.
