Defer freeing of conntrack zone ids until allocation fails
Instead of freeing the conntrack zone ids from removed ports
right before allocating a new one, wait until there is an
allocation error. This removes the overhead from the initial
zone id creation. Since there are 64K zone ids we might not
ever need to clean stale ones anyway.

Add EnvironmentDescription, pass it down
* The EnvironmentDescription class describes an entire fullstack
environment (as opposed to the currently implemented host-only
descriptions). This will allow future patches to signify that a test
should set up an environment that supports tunneling, l2pop, QoS and
more.
* Now, most fullstack fixtures (config and process ones, at least),
expect both the EnvironmentDescription for the current test and the
HostDescription for the 'host' the config/process is on. This allows
for easier and most robust future changes, as now adding a new
parameter to one of the description objects doesn't mean adding that
argument to a number of other objects which are using it.
* Changed HostDescription's default argument of l3_agent to False, since
adding new configurations and defualting them to True forces the
author to go through ALL the tests and explicitly turn them on/off.
However, defaulting new configurations to False only requires
explicitly turning them on, which we ought to do anyway.

Add a fullstack fake VM, basic connectivity test
* Full stack tests' fake VMs are represented via a namespace,
MAC, IP address and default gateway. They're plugged to an OVS
bridge via an OVS internal port. As opposed to the current
fake machine class used in functional testing, this new fake
machine also creates a Neutron port via the API and sets the
IP and MAC according to it. It also sets additional attributes
on the OVS port to allow the OVS agent to do its magic.
* The functional fake machine and the full stack fake machine
should continue to share commonalities.
* The fullstack fake machine currently takes the IP address
from the port and statically assigns it to the namespace
device. Later when I'll add support for the DHCP agent
in full stack testing this assignment will look for the dhcp
attribute of the subnet and either assign the IP address
via 'ip' or call a dhcp client.
* Added a basic L2 connectivity test between two such machines
on the same Neutron network.

instead of replicate a lot of the code. I had to make a
small change to _setup_arp_spoof_for_port since all OVS ports

Fix tenant access to qos policies
fix policy.json to not allow tenants to create policies or rules
by default and allow tenants attach ports and networks to policies,
please note that policy access is checked in the QoSPolicy neutron
object in such case.
The reservation engine is subject to failures due to concurrency;
the switch to pymysql is likely to also have a part in observed
failures. While no gate failures have been observed so far, this
is a time bomb waiting to explode and must be addressed.
For this reason this patch acts conservatively by ensuring the
API controllers do not use anymore reservation. The code for
reservation management is preserved, and will wired again on the
controller when these issues are sorted.
The devref for neutron quotas is updated accordingly as a part
of this patch.
The patch makes L3 agent aware of possible SNAT role
rescheduling to/from it.
The gist is to compare gw_port host change.
If it was changed and agent is not on target host then
it needs to clear snat namespace if one exists. If agent
is on target host it needs to create snat namespace from
scratch if it doesn't exist.
Host field was excluded from gw_port comparison on
agent side as part of HA Router feature implementation.
This code was moved to corresponding module.

invoking the limit_check routine.
The limit_check routine however has not been removed and
depreacated as a part of this patch. In order to ensure all
quota drivers expose a consistent interface, a
make_reservation method has been added to the configuration
based driver as well. This method simply performs "old-style"

Don't fatal error during initialization for missing service providers
Sometime during the split, code was added to fixup driver paths,
which imports service providers even for plugins which are not
in use. That, combined with neutron including default service
providers for VPN and LOADBALANCER, resulted in a really messy
mess in terms of removing VPN from the main neutron test suites.
This change stops the imports, so that if one of the services is
missing, neutron server can still start. It likely breaks the driver
path fixup, which can be fixed outside of this gate blockage.
This merge commit introduces QoS feature into Liberty release of
Neutron.
The feature is documented in: doc/source/devref/quality_of_service.rst
included with the merge patch.
It includes:
- QoS API service plugin with QoS policy and QoS bandwidth limit
(egress) rule support;
- core plugin mechanism to determine supported rule types, with its ML2
implementation;
- new agent extension manager;
- QoS agent extension with pluggable backend QoS drivers (Open vSwitch
and SR-IOV support is included).
To extend network and port core resources with qos_policy_id attribute,
a new ML2 extension driver (qos) was introduced that relies on the QoS
core resource extension (the idea is that eventually we'll get a core
resource extension manager that can be directly reused by core plugins).
Agent-server interaction is based on:
- get_device_details() method that is extended with qos_policy_id;
- a new push/pull mechanism that allows agents and servers to
communicate using oslo.versionedobjects based objects sent on the
wire.
The merge includes the following types of test coverage:
- unit tests;
- functional tests for OVS agent, QoS agent extension, and low level
ovs_lib changes;
- API tests to cover port/network qos_policy_id attribute and new QoS
resources.
This merge also disables qos extension API tests until the service is
enabled in master gate.
Local changes apart from conflicts:
- updated down_revision for qos migration to reflect master expand head;
- disabled qos API tests with gate_hook.sh until we have it enabled in
master gate;
- bumped oslo.versionedobjects requirement to reflect what is in
openstack/requirements' global-requirements.txt
