Convert Azure Pipeline To Stages (#1874)

This is the new model AZP will use going forward.
But it also allows you to retrigger failed stages
before other stages have completed. Thus, if unit
test fails early, or integration test, you can rerun
the stage without having to wait for other stages to
complete.
