Support for independent alembic branches in sub-projects
Sub-projects shall now register their independent alembic migrations
via entrypoints in setup.cfg, and neutron-db-manage will discover them
and run them automatically.
If a service or sub-project is specified explicitly, then
neutron-db-manage will run on only that service or sub-project.
The advanced services project are just special cases of sub-projects.
For example, specifying the CLI option '--service lbaas' is the same
as specifying '--subproject neutron-lbaas'.
Specifying no service or sub-project will cause neutron-db-manage to
run the command on neutron and all installed sub-projects.
Added and consolidated documentation into devref for alembic migrations.

Remove bigswitch mech_driver entry point definition

Improve callback registry devref documentation and usability
Latest developments have revealed that the registry can be misused
under certain circumstances, and that it can be harder to use by
projects that extend Neutron.
This patch improves the devref documentation so that developers know
what to expect.
Fix DVR interface delete by port when gateway is set
When removing a DVR interface by port, the subnet_id
passed to delete_csnat_router_interface_ports is None,
and so it deletes all the DVR SNAT ports for the
router.
This patch fixes this issue by passing in the right
subnet_id to the delete_csnat_router_interface_ports.

Destroy ipset when the corresponding rule is removed
if a security group has a rule which allow a remote group access,
but this remote group has no IPv4 and IPv6 members, L2 agent

id from the diff of pre_sg_members-sg_members, then destroy the ipset

Replace 'import json' with oslo_serialization
Replace remaining occurences of 'import json' with

This patch is in preparation for the integration

added so that ML2 drivers can filter for all
Ironic ports based upon match for 'baremetal'.
Nova/Ironic will set this vnic_type when issuing

Enable fullstack multinode tests, add L3 HA test exemplar

* Split ML2ConfigFixture to the server-side ml2 configuration

* Neutron process logs were using H:M:S format as their file name,
but when starting multiple agents of the same type my machine
was fast enough to do that in the same second so that different
processes were outputting to the same log file. No good!
Added ms to the log name format. I also changed the log time
from UTC to local timezone.
* Renamed and moved 'FullstackFixture' to neutron/tests/fullstack/
resources/environment.Environment
* Added a 'Host' abstraction that groups agents that report with
the same 'host' value. Hosts may be interconnected by the
environment via shared bridges.
* The 'Environment' class will accept global
attributes (This will be later filled with stuff like tunneling,
l2pop or other environment-level flags), and in this patch accepts
a list of host attributes (Configuration that may differ between
hosts like the l3 agent mode [legacy, dvr, dvr_snat]).

works.
