nvp plugin rxtx_factor readonly update port

The following change done in nova 7de916 started passing in the
rxtx_factor on update port rather than just on create_port which
is what we only originally supported. Therefore currently when
booting a vm and specifying --nic port-id it will fail to boot with:
Cannot update read-only attribute rxtx_factor. This patch is a work
around to allow the rxtx_factor value to be passed in on update port even
though we ignore the value. Later we'll implement updating rxtx_factor on
ports but this is a good work around for now.

GRE tunnels should include local_ip.

This addresses the issue of having one or more multi-homed host.

Because you may only specify one local IP for a quantum agent, and
other hosts could be routed across different subnets (even for small
installations, for various reasons), it's important to also specify
the used local_ip when setting up the GRE tunnels. As long as the
address is routable on both ends, this will work. If the local_ip is
not specified, then traffic will mysteriously be dropped on one end
where the IP does not match the expected IP in the GRE tunnel.

LBaaS: add delete_health_monitor() to driver API

Currently there is create_health_monitor() in the driver API so
a driver may create an object on device but there is no delete_health_monitor()
and monitor objects will remain on device forever.
Driver should at least call plugin to delete a db object.
