Define LOG globally in baremetal_deploy_helper

Since LOG = getLogger() has been moved from the global scope
to the function scope (main), the rest of the module could
not find LOG. This patch makes LOG global again.

Add NOVA_LOCALEDIR env variable

Part of fixing bug #995287

Syncs these two commits from oslo-incubator:

  Support overriding oslo localedir too
  Add a gettextutils.install() helper function

to get a new gettextutils.install() function which allows the default
localedir to be overwritten via an environment variable.

Note that gettextutils.install() must be called before any other nova
modules are imported since some modules attempt to translate strings
at import time (e.g. the 'message' attributes on classes in
nova.exception). This is broken and inefficient, but fixing it involves
adding something like spinx's l_() function and would be very invaisve.

Also, note that calling gettextutils.install() in nova.cmd.__init__
means that no program which uses a different translation domain should
ever import any of the modules under nova.cmd.

Remove unnecessary db call in scheduler driver live-migration code

When the scheduler selects a destination host for live-migration, a db
call is made to get instance_type info for the instance. To avoid the
db call, this should instead call instance_types.extract_instance_type
on the instance.

Resolves bug 1167811.

Allow for the power state interval to be configured.

The power state interval right now is hard coded to 600 seconds.
In order to allow deployers to change this timing (and determine)
the side-effects of that change it is useful to allow this value
to be configured instead of static.

Cleans up orphan compute_nodes not cleaned up by compute manager

Fixes bug 1161193

Orphan compute_node records can cause the scheduler to pick
compute nodes that are not handled by driver anymore. This
can happen if you rename your hypervisor_hostname or in a
multi-node support where driver does not support a node
anymore for whatever reason (hardare failure for example).

Also, removing resource tracker logic to delete nodes since
resource trackers built in compute manager will never accept
nodes not reported by driver

Add an extension to show the mac address of a ip in server(s)

This extension adds the OS-EXT-IPS-MAC:mac_addr param
so that users can associate the mac address to the ip of the server in
one API call.

Make compute/manager use conductor for unrescue()

The compute_api.unrescue() call makes direct database queries, which means
it can't be called directly from compute manager. This patch adds support
in conductor for proxying this request and makes compute manager utilize
it.

Make sure confirm_resize finishes before setting vm_state to ACTIVE

Setting it to ACTIVE to early will allow new resize or whatever
operations to start before the current confirm has finished which
might result in all sorts of conflicts.

Resolves bug 1161529 where an intermittent failure in a tempest test
happens because a confirm operation conflicts with a later resize
carried out on the same instance. As the new resize starts to move
around instance disks, the still not finished confirm operation might
fail at recalculating total disk usage due to a missing disk.

Other possible conflicts might be due to system_metadata and/or quota
not being up-to-date at the moment the instance becomes ACTIVE.
