Fix scheduling of DVR routers to not stop scheduling once
csnat portion was scheduled. See bug report for failing
scenario.
This partially reverts
commit 3794b4a83e68041e24b715135f0ccf09a5631178
and fixes bug 1374473 by moving csnat scheduling
after general dvr router scheduling, so double binding does
not happen.

Do not delete fip namespace during l3 dvr agent resync
This was introduced by commit 46608806aa7a9c60214e28429ca5a8b87b2a15de

from external network id rather than router id.
The fix is to ensure fip namespaces for the known routers are kept
by namespace manager on agent resync.

Enable fullstack multinode tests, add L3 HA test exemplar
* Created a 'resources' subdir and moved all fixture files
to it.
* Split ML2ConfigFixture to the server-side ml2 configuration
fixture, and the OVS agent configuration fixture.
* 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]).
* Made OVS agent and L3 agent fixtures expose their bridges
so that I could interconnect them.
* Added a super simple L3 HA test to show that this entire thing
works.

DB, IPAM & RPC changes for IPv6 Prefix Delegation
This patch includes the DB, IPAM & RPC changes needed for the IPv6 Prefix
Delegation feature.
To enable this feature, the subnetpool_id attribute of subnets has been
modified to allow for a special subnetpool identifier - "prefix_delegation".
WORKFLOW:
1. Admin sets default_ipv6_subnet_pool in neutron.conf to "prefix_delegation"
2. User creates a new IPv6 subnet without a CIDR or subnetpool ID
3. User creates an interface between this subnet and a router with an existing
external interface
The agent-side changes will follow in separate patches.
A documentation patch is up for review here:
https://review.openstack.org/#/c/178739

Install arp spoofing protection flow after setting port tag

Move 1c844d1677f7 expand migration to appropriate branch
Commit cb60d0bb4e0cc0cba68f59fdf5f4e89d6ec52950 added an expand

HEAD. This might impact trunk chasers which have already executed
migration 1c844d1677f7 as a part of the contract branch.

Move away nested transaction from _ensure_default_security_group
This patch remove the nested transaction started in
_ensure_default_security_group, before calling create_security_group.
Instead, a nested transaction will be started inside
create_security_group.
The purpose of this change is to reduce the time period in which the db
transaction is open (to avoid races, db lock timeouts, etc), when creating
the default security-group.
OVSBridge was inheriting db_list from BaseOVS, which was
returning the information of all the ports on the machine,
not only the ones belonging to the bridge.
The OVSNeutronAgent was using that method with the assumption
that ports were filtered by bridge.
To avoid confusion, this patch add a new method to OVSBridge
get_ports_attributes to query the info for all the ports
belonging to the bridge.
db_list is removed from BaseOVS since that method is already
available in ovsdb/api.py
ovs_lib methods that use db_list are refactored accordingly.
Since this option is configured in the DEFAULT section of nsx.ini,
the name of the option clashes with that in the networking_l2gw repo.
Proposal is to prefix our option with "nsx_" to avoid such interference.
Unfortunately this module was not moved to openstack/vmware-nsx
during decomposition and therefore this patch is being proposed on
the neutron repository.
