Define devstack services without the test-matrix
Define devstack services without the test-matrix

Emit a disable_all_services and define which service we run in
the job directly. This drops the dependency from the test matrix,
from devstack default list of services and it makes it easier for
jobs to add/remove services based on the list in the base job.
