tripleo containers for technical services lack package "less"

[Damien Ciabrini]

All containerized Openstack services come with the utility "less" in the container image.

But this is not the case for technical services like redis, mariadb, swift, rabbitmq...

There is no explicit inclusion of "less" in tripleo_kolla_template_overrides.j2, and after some digging, it seems that "less" is included in Openstack containers only because of a package dependency. Excerpt from kolla-build mistral:

The technical services don't build on top of openstack-base, so less is never included in those images.

It would be grand if all images could come with "less" built-in.
