Public bug reported:

ECMP is a kind of routing technology which allows multiple different
links reach the same destination. Thanks to ECMP has supported by linux
kernel, neutron can simply support ECMP by using linux command line and
adding route entry into qrouter namespace.

An ECMP entry looks like：
ip route replace to <destination_ip> nexthop via <nexthop_ip1> nexthop via <nexthop_ip2>

Since Octavia has proposed an active-active load balancing design on
https://review.opendev.org/#/c/723864/ and this design need ecmp support
in neutron, I hope ECMP can be supported as soon as possible.
