Use the old pulp-ci-centos:https image with updated service files

This is a temporary workaround that makes the CI green once again. The
referenced image uses the pulp-ci-centos:https base image. On top of it,
there are layers that contain updated service files which allows us to
properly run pulpcore-api and pulpcore-content services.

We will revert the commit once we will be able to resolve the execution
of nested containers.
