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 remove the 'upgrade' job, given that it's been broken
all cycle due to the way the job executes and we need to
regroup to figure out another way to do it.
3. We rename the tox target for 'func_lxc' to 'lxc' and
as the 'func_' prefix is pointless.
4. We remove the base python setting in the lxc tox target
because we're not running our functional tests using py3
yet.
