Cluster verify: don't assume we're verifying all nodes/instances

This commit fixes a few initial simple cases in which it was assumed that
we're always working over the whole cluster. With this change, we
differentiate between "nodes/instances to verify" and "checks that need
cluster-wide information".

In particular:

- retrieve hypervisor parameters always from all instances
  - always specify full node list in NV_NODELIST
  - retrieve OOB path from all nodes
  - verify DRBD devices against the full set of instances (this ensures
    minors get properly verified even if an instance is split between groups)
  - look up node groups against the set of all nodes (to avoid tracebacks
    in case instances are split between groups)
  - determine whether running instances are unknown by checking against the
    full list of instances

Behavior in all cases stays the same if still running over the whole
cluster.
