Use three separate jobs for code coverage diffing
Reusable roles and playbooks are quite important upstream (I have
zuul-jobs inclusion in mind). Besides that, in Zuul's Ansible a playbook
is supposed to come from the same repo as the one where the job
definition is placed, and one can only override a job's `run` playbook.
This makes it rather annoying to modify, say, `tox-coverage` definition.
My previous approach with a job which performed two things (build the
old source *and* then generate coverage report) also would not scale
that well if the build+test phase is long.
Switch to three jobs:
- build the current, proposed state, and gather coverage info,
- build the past state, gather coverage info,
- download two artifacts from previous runs, reproduce the source trees,
and generate the final coverage diff report.
