multinode devstack update for live-migration

Browse Source 
For multinode setup, a couple of updates to /etc/nova/nova.conf was
needed for live migration.

serial_console needed to be disabled and vncserver_listen needed to
be set to any for the vncserver to accept connections from all of the
compute nodes.

Disable serial console
----------------------
Serial console needs to be disabled for live migration to work.
On both the controller and compute node, in /etc/nova/nova.conf
[serial_console]
enabled = False
Alternatively, in devstack's local.conf:
[[post-config|$NOVA_CONF]]
[serial_console]
#enabled=false
VNC server configuration
------------------------
The VNC server listening parameter needs to be set to any address so
that the server can accept connections from all of the compute nodes.
On both the controller and compute node, in /etc/nova/nova.conf
vncserver_listen = 0.0.0.0
Alternatively, in devstack's local.conf:
VNCSERVER_LISTEN=0.0.0.0
