Merge "[CI] Slim down Masakari job"

tests/templates/inventory.j2

 # These initial groups are the only groups required to be modified. The
 # additional groups are for more control of the environment.
+
+# NOTE(yoctozepto): In CI we want to test Masakari HA but not of other services,
+# to conserve the resources. Hence, we set Masakari groups to use both
+# primary and secondary while the parent group (control) uses only primary.
