When the percona-cluster charm sets an access-network but the default
unit-get address is not on that network extra shared-db relations get
executed. This is specifically a problem when running upgrades and
trying to avoid API downtime.
The root cause is that the access-network is not checked until the
SharedDBContext is consulted. But then db_joined function will
change it back to the wrong ip on subsequent runs.
This change adds a check for access-network on the relation during
the db_joined function and pushes IP selection off to get_relation_ip.
Charm helpers sync to pull in changes to get_relation_ip.

In order to support changes in the api-paste.ini file for the keystone
middleware of the neutron-api service by subordinates we need a generic
mechanism to pass wsgi middleware data via a relation.
The following approach is used in this change:
- relation data set by subordinates:
{'extra_middleware': [{
'type': 'middleware_type',
'name': 'middleware_name',
'config': {
'setting_1': 'value_1',
'setting_2': 'value_2'}}]}
- there may be many subordinates each with their own set of middleware
all of which should be taken into account
- besides a factory method for middleware other settings can be
specified, therefore, a generic config dictionary is used
- neutron-server has to be restarted as api-paste.ini is read upon
startup of the service
- api-paste.ini rendering code is added along with a template code
containing loops over a list of middleware provided in a context to
construct the following entries:
keystone = [name-1 ... name-m] <default_middleware>
[type-1:name-1]
key-1 = value-1
...
key-n = value-n
...
[type-m:name-m]
key-1 = value-1
...
key-k = value-k
- api-paste.ini defaults are copied from their respective upstream
neutron branches

neutron-api was still using the old approach to status assessment,
calling the os_set_workload_status function rather than the provided
assess_status function in neutron_api_utils.
Switch to using assess_status, which also correctly sets the
application version for the application.

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.

Add a new configuration option to enable SR-IOV support across Neutron and
Nova; this involves enabling the required mechanism driver, and informing
the nova-cloud-controller charm that SR-IOV has been enabled, so that Nova
can use the correct scheduler filters for PCI device management.

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'.

Earlier versions of the nova-cloud-controller charm controlled
upgrades of the neutron databases; this has now been dropped
from the nova-cloud-controller charm.
Drop logic around conditional migration related to OpenStack
releases and always migrate the neutron database, so long as
the unit is the lead unit.

This advertises API readiness to subordinates via a new flag int the subordinate
relation. It determines readiness by the completion of required contexts. This
simply means the API service has enough of its topology completed to begin
servicing requests, and it has at least *started* the service (from the POV of
the init system). Its up to the subordinate service to ensure the API is
functional.
It also allows subordinates to specify custom api_extension_paths to neutron-api.
