Now that we're using the general templates, we can slim down
the role test definitions. We can also remove tests which are
not being watched, or which are fundamentally broken. With
this we can also remove unused scripts/plays.
We do the following:
1. We remove the 'ssl' job, given that the person working on
that is no longer doing so, and no-one else has picked up
the work.
2. We revert the use of project templates to using job config
directly, given that nothing other than Ubuntu is supported.
