Enable testing of Security Proposed PPA

[coreycb]

We are deploying the same bundles here as are in the distro-regression directory, however in this case, the security proposed PPA will be enabled on all units. Notice that no cloud archive releases are included here because the security proposed ppa only needs testing from "distro".

These tests will be run weekly in zuul based on the osci.yaml updates.

These tests can also be run via tox, for example: tox -e security-distro-regression jammy-yoga

I pinned juju to 2.9 in this PR: https://github.com/openstack-charmers/charmed-openstack-tester/pull/108 -- it's pulling juju 3.1 which we may not want to do yet.
