Remove availability_zones from service table

This is the final step in enabling availability_zones using aggregate
metadata. Previously all services had an availability_zone, but the
availability_zone is only used for nova-compute.  Services such as
nova-scheduler, nova-network, nova-conductor have always spanned all
availability_zones.

After this change only compute nodes (nova-compute), will have an
availability_zone. In order to preserve current APIs, when running:
* nova host-list (os-hosts)
* euca-describe-availability-zones verbose
* nova-manage service list
Internal services will appear in there own internal availability_zone
(CONF.internal_service_availability_zone)
Internal zone is hidden in euca-describe-availability_zones
(non-verbose)

CONF.node_availability_zone has been renamed to
CONF.default_availability_zone and is only used by the nova-api and
nova-scheduler. CONF.node_availability_zone still works but is
deprecated
