All contributors to this charm have agreed to the switch
from GPL v3 to Apache 2.0; switch to Apache-2.0 license
as agreed so we can move forward with official project status.

The nova-api-metadata service which runs in the neutron-gateway
charm units will shutdown if it does not receive a response from
a nova-conductor within a short timeout period; this can happen
if the nova-conductor is not yet wired to the messaging bus.
Trigger a remote restart using the existing relation api when
the amqp relation is complete, and nova-conductor services should
be (shortly) up and running.

Implement DNS high availability. Pass the correct information to
hacluster to register a DNS entry with MAAS 2.0 or greater rather
than using a virtual IP.
Charm-helpers sync to bring in DNS HA helpers

The neutron-gateway charm operates a nova-api-metadata service
for instance access to Nova metadata; this needs to be restarted
after a database initialization as if the conductors are not
responding, this service will shut itself down.
Set a remote_restart nonce on the quantum-network-service
relation post database migration to trigger remote restarts.

To ensure that the charm presents the right IP address for
accessing the MySQL database over the shared-db relation,
ensure that any network space binding provided by the user
is preferred over the default of 'private-address'.
If network spaces is not supported (juju < 2.0), fallback to
using 'private-address'.

Neutron functionality was deprecated last release; remove
direct support for managing the neutron-server process and
associated plugin support from this charm.
All neutron-server support is now provided by the neutron-api
charm.

Add charmhelpers.contrib.hardening and calls to install,

Rollup all old configuration file templates, remove any related
to Quantum which was renamed in the Havana release.
Drop references in code to Quantum, refactor unit tests to baseline
on Icehouse rather than anything older.
Drop relation and associated references to nova-volume service;
deprecated in Folsom and removed in Havana.
Drop ml2 migration - this was required when migrating to Icehouse
from older releases.

Mitaka requires the use of a separate nova-api database;
ensure that this is setup on the shared-db relation and add
a new [api_database] section to the mitaka nova.conf file.
Add a new NovaAPISharedDBContext wrapper to prefix the key
names for the nova-api database with 'nova_api_' so that we
can present two database connections to the same configuration
file.
Ensure that 'nova-manage api_db sync' is called for database
setup for >= mitaka release.
For upgrades, ensure that the database migration and service
start is deferred until the nova_api database has been
setup by the related mysql service.

Advertise Nova API readiness
Adds a new relation 'nova-api' that can be used by services that consume
the nova api in some way or another. We use it to simply pass a flag to
remote services that states whether the API service is ready to be used,
based on the complete context of required interfaces.
This change adds the appropriate region information to the conf files
and to the cloud-compute relations in order to ensure that the region
can be configured on all nova components.

Fix upgrade breakage whereby if upgrading from
version of charm that did not support
dbsync_state peer setting db ops get stuck
waiting infinitely for db to be intialised.
