The following changes have been made to coordinate with the changes
made in Neutron for Pike:

* Partial use of Neutron context has been completely moved to neutron_lib's
context.

* The patching of neutron.db.api.get_session() has been replaced with
patching of sqlalchemy.orm.session to add the notification_queue attribute.
This significantly reduces the earlier complexity of patching.

* Use of top-level start of transaction in GBP plugins:
with context.session.begin(subtransactions=True):
has been migrated to use of:
with db_api.context_manager.writer.using(context):
or
with db_api.context_manager.reader.using(context)
as relevant.

* Calls to _make_resource_xxx_dict() in GBP plugins have been moved
to inside the transaction.

* The use of:
neutron.callbacks.events
neutron.callbacks.exceptions
neutron.callbacks.registry
to
neutron_lib.callbacks.events
neutron_lib.callbacks.exceptions
neutron_lib.callbacks.registry

* The use of:
neutron.api.v2.attributes.resource_xxx
neutron.extensions.extension_xxx
to:
from neutron_lib.api.definitions.resource_xxx
from neutron_lib.api.definitions.extension_xxx
resp.

* The use of:
neutron.db.db_base_plugin_v2.NeutronDbPluginV2.register_dict_extend_funcs
to:
neutron.db._resource_extend.resource_extend
(the latter is a decorator)

* The use of:
neutron.db.db_base_plugin_v2.NeutronDbPluginV2.register_model_query_hook()
to:
from neutron.db import _model_query as model_query.register_hook()

* The use of:
neutron.db.segments_db.NetworkSegment
to:
neutron.db.models.segment.NetworkSegment

* In the case of Neutron ml2plus plugin (used by APIC/AIM solution),
the use of get_admin_context() has been patched to return elevated
version of the current context in use. This helps to preserve the session
and transaction semantics. Ideally, context.elevated() would have been
directly used in all these places, however the current context is not
available in these places, and hence getting the current context and elevating
it is wrapped in the get_admin_context() patched method.

* In the case of the components used by the APIC/AIM solution (including
the ml2plus and l3_plugin) the use of:
with context.session.begin(subtransactions=True):
to
with db_api.context_manager.writer.using(context):
or
with db_api.context_manager.reader.using(context):
as relevant.

* Patching of methods from Neutron which is no longer relevant have been
removed from gbpservice.neutron.extensions.patch module.

* Setting up of UTs has been fixed to load and reset configurations
appropriately. This helps to eleminate some failures when tests are
run in non-deterministic orders.

* In tree devstack plugin has been updated (aim repo commit pin needs
to be reverted).

* Gate jobs have been updated as relevant (including fixes to the exercise
scripts and job configurations).

The associated repos, namely, client, UI and automation have also been
updated (the reference to the client's gerrit patch needs to be updated
once the patch has been merged).
