l3ha don't set backup qg ports down

[Edward Hope-Morley]

The history to this request is as follows; bug 1916024 fixed an issue that subsequently had to be reverted due to a regression that it introduced (see bug 1927868) and the original issue can once again present itself in that keepalived is unable to send GARP on the qg port until the port is marked as UP by neutron which in loaded environments can sometimes take longer than keepalived will wait (e.g. when an l3-agent is restarted on a host that has hundreds of routers). The reason why qg- ports are marked as DOWN is because of the patch landed as part of bug 1859832 and as I understand it there is now consensus from upstream [1] to revert that patch as well and a better solution is needed to fix that particular issue. I have not found a bug open yet for the revert hence why I am opening this one.

------------

[Impact]
Please see LP bug description for full details but in short, this patch is a revert of a patch that has show instability in the field for users of Neutron L3HA.

[Test Plan]
  * Deploy Openstack with Neutron L3 HA enabled
  * Create a number of HA routers
  * Check all qrouter namespaces and ensure that the qg- port is UP in all

[Regression Potential]
Since the original patch was intended to address issues with MLDv2 it is possible that reverting it will re-introduce those issues and a new patch will need to be proposed to address that.

[Stefan Hoffmann (mr-hopeman)]

We can not simply revert bug 1859832 , as we than still face issues due to MLDv2 and other discovery related problems.
Instead, we should discuss a solution to either
rework [1], e.g. by let keeplived take the interface up and down or
find the traffic creating issues and block this, e.g. via iptables.

[Edward Hope-Morley (hopem)]

One caveat I have found with this revert is that after upgrading my l3-agent and restarting it, the qg port remains down for existing routers and this is because without this patch the agent (a) assumes that it set the port UP when it created the port and (b) if the port exists on restart it doesn't change it - all if which is expected. So, to resolve this you can either reboot your node, manually set the port to UP or you can do a --disable/--enable on the router using the openstack client. Personally i'd say manually setting the ports to UP is the quickest and least disruptive e.g.

ip netns exec snat-4fb550fd-7893-4a49-b0ec-8fc0b4dc3561 ip link set dev qg-359697da-7d up
