Since the --master-netdev option is now used both at cluster init and at
cluster modify time, it cannot have a default value of DEFAULT_BRIDGE
(xen-br0) anymore. As such at cluster init we make the initialization
explicit if another value hasn't been passed. This fixes gnt-cluster
modify changing the master_netdev to xen-br0 if called without that
argument.

This allows “gnt-node list” to show the difference between modes marked

master, node2's node daemon crashed and node3 is marked offline:

Changing the volume group is a lot less frequent than acting on a node
group. As such we drop the "-g" shortcut and require the long option to
be passed. In 2.3 the commands which used to accept the volume group as
"-g" won't have any node group option, so no confusion will arise. Later
on we may pass "-g" as the initial node group name to gnt-cluster init,
although that's not strictly necessary, as modifying it later is always
possible.

This patch adds an initial implementation of a lock monitor, accessible
for the user through “gnt-debug locks”. It currently shows all resource
locks: BGL, nodes and instances. Config and job queue locks could be
shown too, but wouldn't be of much help.  The current owner(s) and mode
are also shown.

Showing pending acquires will require further changes on the SharedLock
internals and is not yet implemented.

Example output:
$ gnt-debug locks -o name,mode,owner
Name            Mode      Owner
BGL/BGL         shared    JobQueue19/Job147
instances/inst1 exclusive JobQueue19/Job147
instances/inst2 -         -
instances/inst3 -         -
