Run tests for older releases periodic-weekly

Openstack releases older than Yoga are now in
extended maintenance. To reduce the CI
footprint we don't run test jobs for older
relases as part of the check/gate pipelines.

Instead we are going to run those jobs as
part of the periodic-weekly pipeline.

See the detailed description of extended maintenance
status here
