octavia driver agent is missing

[Michal Nasiadka]

Octavia to support 3rd party providers needs octavia-driver-agent to be running
Kolla-Ansible does not deploy an octavia_driver_agent container with shared volume for /var/run/octavia

    Add missing octavia-driver-agent

    For using 3rd party Octavia providers (such as OVN provider) an
    octavia-driver-agent container must be running to expose those providers to
    use.

    tasks that used item.value.group where updated to not fail on missing group
    (to not break existing user inventories)

    OVN CI job has been extended with deploying Octavia and testing OVN Load
    Balancer.
