Nova recently introduced an issue that breaks FFU due to requiring
new compute service records to be recorded before control services are
allowed to start. However the former depends on the latter, which
creates an unsatisfiable circular dependency. Since this has been
both released and backported, Nova introduced a workaround config flag
specifically to get out of that loop, which we set here if needed.
