This enables IPv6 routes are updated in kernel with NLM_F_REPLACE flag whenever there is route update instead of treating route update as delete and add.

- What I did
Enable IPv6 Route semantics in zebra by starting zebra with command line option --v6-rr-semantics
This enables IPv6 routes are updated in kernel with NLM_F_REPLACE flag
whenever there is route update from zebra instead of treating route update as
delete and add.
- How I did it
Adding --v6-rr-semantics option to frr docker supervisor.conf
- How to verify it
Create ECMP IPv6 static routes with multiple nhops.
- Description for the changelog
- Steps to recreate
In FRR:
