Basics of TCUP that is used OUTSIDE of RefStack to run RefStack

This simple set of scripts will
1) build a usable RefStack container
2) assemble the correct environment variables and other run command params
3) run the container in the background
4) provide the user the right command to attach to the container

TODO:
1) the link to the dockerfile should be a URL, update AFTER patch accepted
2) the command to start tempest is NOT working, needs to get fixed
