Rename range to avoid shadowing the builtin

better to apply this consistently in this file as a separate refactor

The ML2 RPC version 1.1 breaks the hyper-v agent and
consequentially the RPC version in the Hyper-V agent needs
to be set to 1.1 to match the ML2 RPC base API version.

DVR introduces a new namespace type called snat-<router_id>. These

Use jsonutils instead of stdlib json
jsonutils provides multiple benefits in comparison to pure stdlib json

Similar patch was already merged before [1], but since it lacked hacking

This patch switches all the code to using jsonutils and adds a hacking

The hacking rule requires that jsonutils module does not mimic as 'json'

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.
Fix PortNotFound error during update_device_up for DVR
An agent's request to update the ARP entry for a VM port

been added, which required a minor refactoring of the
test case class, in order to accommodate the use of
side effects for the objects being mocked.

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.

Preserve link local IP allocations for DVR fip ns across restart
The L3 agent allocates link local address pairs used in connecting the
routers to the floating ip namespace. When those allocations are
forgetten by restarting the L3 agent they all get rewired on restart.
This change preserves the allocations using a file in the local file
system. Storing them in the database would be overkill and would
affect system performance.
The metadata agent was unable to find networks
attached to the DVR router because it was only
filtering ports for 'centralized' routers.
To fix the issue, this patch expands the search
filters to include DVR router interfaces during
the network lookup operation.
The extra filter cause no evident performance
loss while serving the request; a different
approach would require to pass the router type
around to narrow down the search filter, but it
sounds like an overkill.
