Hi Neutron Team

I was bug deputy in neutron last week.

Summary
==========
3 bugs need more attention, one is related to db upgrade (upgrade from Rocky to Stein), one bug is an issue between Nova and Neutron and related to network-vif-plug event, and one seems to be related to IPv6 Metadata.
If you have time please check them and help solve them and check the reviews I linked.
