[FFE] Add support for multiple gateway management + BFD/ECMP

[James Page]

The 2024.1 Caracal release of Neutron (already in archive) includes features to enable multiple gateway management + associated BFD and ECMP monitoring and multipathing for external networking in OpenStack.

The command line tooling for this was committed after the 6.6.0 release of the openstackclient project; in order to expose this features to OpenStack users on Noble we should pull in the four patches require to add the sub commands and configuration options for networking.

Neutron feature details:

bug 2002687

Merge detailing patches:

Build logs:

https://launchpad.net/~fnordahl/+archive/ubuntu/dev/+build/28041314

Testing confirmation:

Using the package from the above build test:
$ dpkg -l | grep python3-openst
ii python3-openstackclient 6.6.0-0ubuntu1.0 all OpenStack Command-line Client - Python 3.x

I can successfully run the following script that makes use of the functionality:
ROUTER=router10
openstack router create \
    $ROUTER \
    --disable-snat \
    --external-gateway net1 \
    --fixed-ip subnet=subnet1,ip-address=10.50.111.100 \
    --external-gateway net1 \
    --fixed-ip subnet=subnet1,ip-address=10.50.111.101 \
    --external-gateway net2 \
    --fixed-ip subnet=subnet2,ip-address=10.170.175.100 \
    --external-gateway net2 \
    --fixed-ip subnet=subnet2,ip-address=10.170.175.101 \
    --external-gateway net3 \
    --fixed-ip subnet=subnet3,ip-address=10.199.89.100 \
    --external-gateway net3 \
    --fixed-ip subnet=subnet3,ip-address=10.199.89.101 \
    --enable-default-route-bfd \
    --enable-default-route-ecmp
