ceph-pr-api: update to run in a container (via bwc)

Update the ceph-pr-api tests so that the build and tests that this job
runs are done so inside a container.

The build task is updated to be more similar to how builds are typically
done now for 'make check', with a few tweaks.

Then for running the tests we reuse the build container image created
for the build, install a few extra (ephemeral) dependencies in it and
then fire off the dashboard script that runs the api tests.
