Unless I'm missing something, devstack is also impacted in these
scenarios and doesn't account for installing master branches of select
dependencies. As a result we are seeing failures in our external CI jobs
(that use devstack) due to invalid package versions.

Is the proper way to address this to specify the _REPO and _BRANCH in
our project's devstack lib sciprt(s) as needed so that devstack will
grab master for them?

Thanks
