so personally i would expect the majority of neutrons gate jobs to used the released versions
but we proablly coudl have a neutron-next jobs that was bassically the full tempst job that specifically used master

that is basically what we do with os-vif.
nova uses os-vif form pip
we have an experimental job we can run to use os-vif form souce on any nova chagne and
obviosly os-vif itself uses os-vif from gerrit + nova master

we dont use os-vif master in the default nova jobs but we could if it was needed.
sofar that has not been an issue since we have the experimental job we can alway do
a spot check.
