What do you mean by gap in coverage?
We have scenarios on purpose, so we can horizontally scale the
coverage across multiple jobs and run the jobs only when we need (e.g.
touching telemetry files for scenario001).

Please elaborate on what isn't covered by scenario001, because we
already cover Gnocchi, Panko, Aodh and Ceilometer (with RBD backend
and soon with Swift backend in scenario002).
