Add hook scripts for the functional infra job
Infra jobs support hooks to customize behavior. This change adds
scripts that are intended to be called by the neutron-dsvm-functional
jobs as hooks. Defining hook behavior in-tree instead of directly in
the job definition has the advantage of allowing changes in hook
behavior to be tested before merge.
The gate_hook.sh script added by this change installs a rootwrap
filter to allow functional tests to destroy python processes that
they have spawned. The tests use the python executable provided by
their tox env, and the default rootwrap configuration does not
support killing processes launched by non-system python executables.
This change will have to merge to master and stable/icehouse before
the supporting infra config change can be merged:

Implements securitygroup extension for nuage plugin
In Nuage VSP, the scope of vport-tag(Neutron securitygroup equivalent) is either
per router or per subnet whereas securitygroup scope in Neutron is per tenant.
Because of this, the mapping between neutron and VSP resource always happens at
the port create or update time, such that port's router/subnet is known and
thus sg attachment point in VSP is known.
On port-update --security-group sg1, if this is the first port getting attached
to that security-group, corresponding vport-tag(for sg) and rules( for sg rules)
are created on VSP. Subsequent port-update for the same sg1 will just update the
port to vport-tag binding. When security-group and security-group-rules are
deleted on neutron, corresponding vport-tag and rules are deleted on the VSP.

Delete DVR namespaces on node after removing last VM
After removing the last VM using a distributed router,
the router's namespaces are still present on the VM host
The problem is that the neutron API server sent the router
remove notification to the L3 agent using the name of the
host running the L3 agent instead of the agent's uuid. This
caused an error when sending the notification. So the L3
agent never had the chance to cleanup the namespace.
This problem is fixed here.
Afterwards, it was found that the notification was still not
sent. The reason is that the router/L3-agent binding has
already been deleted before the routine that sends the
router removed notification was called. The notifier routine
errored out when it tried to delete the same router/L3 agent
binding. This problem is fixed in this patch by removing the
binding removal step from the DVR scheduler.

Option to remove routers from dead l3 agents
Add a configuration-enabled periodic check to examine the
status of all L3 agents with routers scheduled to them and
admin_state_up set to True. If the agent is dead, the router
will be rescheduled to an alive agent.
Neutron considers and agent 'dead' when the server doesn't
receive any heartbeat messages from the agent over the
RPC channel within a given number of seconds (agent_down_time).
There are various false positive scenarios where the agent may
fail to report even though the node is still forwarding traffic.
This is configuration driven because a dead L3 agent with active
namespaces forwarding traffic and responding to ARP requests may
cause issues. If the network backend does not block the dead
agent's node from using the router's IP addresses, there will be
a conflict between the old and new namespace.
This conflict should not break east-west traffic because both
namespaces will be attached to the appropriate networks and
either can forward the traffic without state. However, traffic
being overloaded onto the router's external network interface
IP in north-south traffic will be impacted because the matching
translation for port address translation will only be present
on one router. Additionally, floating IPs associated to ports
after the rescheduling will not work traversing the old
namespace because the mapping will not be present.
Remove SELECT FOR UPDATE use in ML2 tunnel driver add_endpoint
SELECT FOR UPDATE expression, which is triggered with the use of the
SQLAlchemy Query object's with_lockmode('update') method, is
detrimental to performance and scalability of the database
performance code in Neutron due to the lock contention it produces.
SELECT FOR UPDATE can be entirely avoided in add_endpoint methods
with the use of single-shot SELECT and INSERT expressions and the
correction of VxlanEndpoint primary key: indeed previously it was not
possible to create multiple endpoints with the same ip, now the model
primary key constraint ensures it.
Method sync_routers is used by the L3 agent to query
routers it knows about. Routers and GW ports lists
are populated in two different times, which means that
they can be interleaved by a delete request which
results in gateway ports being missing in one of the
two data structures.
