Add generic tox job (multiple playbooks)

Here we now support 3 tox jobs; cover, linters and py27.

As you can see by looking at the code, we are not defining any
variables (vars) in .zuul.yaml. This means, we create 3 separate
playbooks (tox-cover.yaml, tox-py27, tox-linters.yaml) which then
contain the variables we need for our tox role.
