Revert "RFC: allow to set configuration and/or specific testcases"

Fix error message reported by Pau:
  docker: invalid reference format: repository name must be lowercase.

This happens in the "docker run" command after the "Starting container
to merge logs" message, because the arguments to --entrypoint are not in
quotation marks. The command fails.

Logs were merged anyway, because
If03422bb8fb126fe6f204a4f8bc6edf0cbb7f194 had already reverted half the
patch and added the log merging back to the Dockerfile.

This reverts commit 73663b01f2.
