Lbaasv2 cookie sessions not working as haproxy( which is backend for lbaas) no longer supports appsession

[kishore surapathi]

I have deployed lbaasv2 and launched bunch of load balancers.

For one of them, I need to configure cookie sessions. When I added it through cli

neutron lbaas-pool-update poolid --session-persistence type=dict type=APP_COOKIE,cookie_name=sessionid

I see errors in logs stating "appsession" is no longer supported by haproxy

Seems appsession is deprecated in haproxy but lbaas still uses it configure the sessions in the backedn haproxy configs

Tried editing it manually in backend but lbaas quickly overwrites it.

Confirmed, this "appsession" option was removed in haproxy >= 1.6 per http://cbonte.github.io/haproxy-dconv/1.6/configuration.html#4.2-appsession

The namespace haproxy driver jinja needs to be updated to use stick tables instead of appsession.

This jinja can probably be copied from the octavia driver as it uses the stick table syntax.

Abandoned after re-enabling the Octavia launchpad.
