Catch InstanceNotFound exceptions for V2 API instance_actions

Use the common.get_instance method to get the instance object
in the V2 API instance_actions extension rather than call
the compute api directly. The utility function
handes InstanceNotFound exceptions and tranlsates them to HTTPNotFound
rather than letting them propagate up causing a traceback.

Fix Jenkins translation jobs

The jobs nova-propose-translation-update and
nova-upstream-translation-update do not update from
transifex since our po files contain duplicate entries where
obsolete entries duplicate normal entries.

Remove all obsolete entries to fix the jobs.

Require admin context for interfaces on ext network

Currently any user can attach an interface to a neutron
external network, if the neutron plugin supports the port
binding extension.
In this case, nova will create neutron ports using the admin
client, thus bypassing neutron authZ checks for creating ports
on external networks.

This patch adds a check in nova to verify the API request has an
admin context when a request for an interface is made on a
neutron external network.

Revert object-assuming changes to _post_live_migration()

Change I140bfec2a52bf659a725a7dbe78ba5c527ed26de converted the
_post_live_migration() call to assume it was passed an object
because the post_live_migration_at_destination() method uses them.
However, it is also called from live_migration() on the source,
which clearly is still using instance dicts.

This patch reverts the changes that assume an instance object,
as well as the tests that were changed as a result. It also
changes the clear_events_for_instance() call to use dict syntax,
since that is called from the live migration path currently.
