1) add a `kolla-ansible` parameter to the [build command](https://github.com/BeyondTheClouds/enos/blob/bdf4ae2ed4356d70cc2b7fdda31e5accfe55739a/enos/cli.py#L553). Ideally it should default to [`services.kolla.KOLLA_PKG` ](https://github.com/BeyondTheClouds/enos/blob/bdf4ae2ed4356d70cc2b7fdda31e5accfe55739a/enos/services/kolla.py#L19) 2) add a templatized `kolla-ansible` in the [build template](https://github.com/BeyondTheClouds/enos/blob/bdf4ae2ed4356d70cc2b7fdda31e5accfe55739a/enos/utils/build.py#L6-L22) 3) remove deprecated [`kolla_ref` and `kolla_repo`](https://github.com/BeyondTheClouds/enos/blob/bdf4ae2ed4356d70cc2b7fdda31e5accfe55739a/enos/utils/build.py#L15-L16)
