The table "router_extra_attributes" is a child of "router" table.
Each register contains extra information that completes the router
description. When using ML2/OVS mechanism driver, the methods that
create and populate the "router_extra_attributes" register are always
called from the L3 DVR, L3 HA and availability zones extensions.
When using ML2/OVN, those extensions are not loaded and therefore the
"router_extra_attributes" register is not created.
Despite this register is currently not used in ML2/OVN (it will be in
future features), there are some project expecting the
"router_extra_attributes" register to be always created (for example,
neutron-dynamic-routing [1]).
This patch enforces the child register creating always when a router is
created. This register is populated with the default values. This new
register does not affect any current operation related to ML2/OVN nor
ML2/OVS.
There is a 1:1 relationship between "routers" and
"router_extra_attributes". The child register is deleted by the database
engine when the "routers" register is deleted (ondelete="CASCADE").

If not set availability_zone_hits when create router, should use
configuration parameter default_availability_zones.
At present, only the creation parameters are validate, and the default
availability zones not validate.
Creating a network is the same as creating a route.

The _resource_extend module is already rehomed into neutron-lib and is
shimmed in neutron. This patch removes the module as no active
consumers are using it.

Commit I81748aa0e48b1275df3e1ea41b1d36a117d0097d added the l3 extension
API definition to neutron-lib and commit
I2324a3a02789c798248cab41c278a2d9981d24be rehomed the l3 exceptions,
while Ifd79eb1a92853e49bd4ef028e7a7bd89811c6957 shims the l3
exceptions.
This patch consumes the l3 api def by:
- Removing the code from neutron that's now in lib.
- Using lib's version of the code where applicable.
- Tidying up the related unit tests as now that the l3 api def from lib
is used the necessary fixture is already setup in the parent chain when
setting up the unit test class.

neutron-lib now contains the API definitions for neutron's core
resources. This patch removes the constant core resource and collection
variables and uses them from lib. Subsequent patches will consume the
actual core resource attribute definitions.

The well known service type constants are in
neutron_lib.plugins.constants, but for legacy reasons a few still exist
and are referenced from neutron_lib.constants that we'd like to remove.
This patch switches references over to neutron_lib's plugin constants.

The callback modules have been available in neutron-lib since commit [1]
and are ready for consumption.
As the callback registry is implemented with a singleton manager
instance, sync complications can arise ensuring all consumers switch to
lib's implementation at the same time. Therefore this consumption has
been broken down:
1) Shim neutron's callbacks using lib's callback system and remove
existing neutron internals related to callbacks (devref, UTs, etc.).
2) Switch all neutron's callback imports over to neutron-lib's.
3) Have all sub-projects using callbacks move their imports over to use
neutron-lib's callbacks implementation.
4) Remove the callback shims in neutron-lib once sub-projects are moved
over to lib's callbacks.
5) Follow-on patches moving our existing uses of callbacks to the new
event payload model provided by neutron-lib.callback.events
This patch implements #2 from above, moving all neutron's callback
imports to use neutron-lib's callbacks.
There are also a few places in the UT code that still patch callbacks,
we can address those in step #4 which may need [2].

By registering functions directly we cut off the dependency of the
"resource extend" functions on the plugin. This is a step towards
the goal of removing the CommonDbMixin mixin class.
Also, we register all "resource extend" functions at plugin create
(in __new__) instead of in the class definition (which caused the
hooks to be registered on import). This ensures the "resource
extend" functions are only registered for the plugins/mixins that
are actually used.
Note that decorators are used to register "resource extend" methods,
similar to the callback receiver decorators.

This adjusts the extra router attributes mixin to add
a new function to explicitly set the value of an extra
attribute. The mixins that depend on extra attrs
now explicitly call this instead of depending on a big
inheritance chain of calling _process_extra_attr_router_create.
This will allow the router_az, DVR and HA modules to eventually
be separated from the L3 plugin class inheritance entirely.

This patch adds a joined relationship from the routers
to the agent table to prevent excessive DB lookups of the
agent availability zones during router listings.
This fix is the same as the one for networks here:

A follow-up patch will add an AZ table so this doesn't

The previous code was doing a DB lookup for each network's
availability zone which was significantly impacting the
performance of network listings.
This patch adjusts the network model to be automatically joined
to the DHCP agents table that the AZ code uses to populate the
AZs for the network.
