Replace binding:capabilities with binding:vif_details
In addition to binding:vif_type, the neutron core plugin needs to
supply various information to nova's VIF driver, such as VIF security
details and PCI details when SR-IOV is being used. This information is
read-only, requires admin privileges, and is not intended for normal
users. Rather than add separate mechanisms throughout the stack for
each such requirement, the binding:capabilities port attibute, which
is a dictionary and is not currently not used by nova, is renamed to
binding:vif_details to serve as a general-purpose mechanism for
supplying binding-specific details to the VIF driver.
This patch does not remove or replace the CAP_PORT_FILTER boolean
previously used in binding:capabilities. A separate patch should
implement the specific key/value pairs carried by binding:vif_details

L3 agent fetches the external network id once
Rather than fetching the id of the external network each time that
_process_routers is called, get it once and remember it. If the agent
is ever requested to connect to a different ext-net then it will fetch
the current ext-net to double check for the unlikely event that the
ext-net has changed. If it has then it will remember the new ext-net.
This is only applicable in the case where there is only one ext-net
that has not been configured explicitly in the config file. That was
the only case that would cause an RPC message in the first place.
This patch changes get_vif_port_set in order to not return
OVS ports for which the ofport is not yet assigned, thus avoiding
a regex match failure in get_vif_port_by_id.
Because of this failure, treat_vif_port is unable to wire
the port.
As get_vif_port_by_id is also used elsewhere in the agent, it has
been enhanced in order to tolerate situations in which ofport might
have not yet been assigned.
The ofport field is added to the list of those monitored by the
SimpleInterfaceMonitor. This will guarantee an event is generated
when the ofport is assigned to a port. Otherwise there is a risk
a port would be never processed if it was not yet ready the first
time is was detected. This change won't trigger any extra processing
on the agent side.
Finally, this patch avoids fetching device details from the plugin
for ports which have disappeared from the OVS bridge. This is a
little optimization which might be beneficial for short lived ports.

Add migration support from agent to NSX dhcp/metadata services
This is feature patch (3 of 3) that introduces support for
transitioning existing NSX-based deployments from the agent
based model of providing dhcp and metadata proxy services
to the new agentless based mode. In 'combined' mode, existing
networks will still be served by the existing infrastructure,
whereas new networks will be served by the new infrastructure.
Networks may be migrated to the model using a new CLI tool
provided, called 'neutron-nsx-manage'. Currently the tool
provides two admin-only commands:
neutron-nsx-manage net-report <net-id-or-name>
This will check that the network can be migrated and returns
the resources currently in use. And:
neutron-nsx-manage net-migrate <net-id-or-name>
This will move the network over the new model and deallocate
resources from the agent. Once a network has been migrated
there is no turning back.
The NSX plugin does not allow to reassociate a floating IP to
a different internal IP address on the same port where it's
currently associated.
