Need to remove usage of novaclient.v2.security_group_rules

[Javier Peña]

python-novaclient has removed the deprecated security_group_rules APIs in https://review.openstack.org/447707 . These are still being used by openstackclient (see [1]), so it will fail when a new novaclient version is released.

This also affects Horizon, which uses novaclient.v2.security_group_rules in https://github.com/openstack/horizon/blob/master/openstack_dashboard/api/nova.py#L36

Question to nova team from horizon side.
From nova team perspective, what is the recommended way if horizon supports Nova security group?
If horizon needs to talk nova micro-versioning API directly, it makes nova-network support difficult. Is it time to drop nova-network support in horizon?

I sent a mail to -dev ML regarding nova-network deprecation policy.

This really can not be removed as unlike Horizon, we support clouds going back quite a ways (officially only those not EOL but OSC works back past kilo for many things)

We will need to re-implement these functions to support clouds deployed with nova-net.
