Create a new --no-voting option for masterfailover

This allows failing over in certain corner cases, such as a 2 node

this dangerous option and how to recover from this situation.

gnt-cluster modify: fix --no-lvm-storage

Currently doing a gnt-cluster-modify --no-lvm-storage is silently
ignored, as it passes a None value in vg_name, which is the same as not
modifying that parameter. Explicitely set the passed value to '', so the
non-true not-None value can be evaluate to actually remove a volume...

Fix gnt-cluster getmaster on non-master nodes

The current implementation of “gnt-cluster getmaster” doesn't work on

gnt-cluster, pass hvparams directly to dict()

If hvparams is not set it will be [], so dict() will transform it to an
