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

This simple set of scripts will
1) build a usable RefStack container using the /scripts/dockerfile
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
5) could be used WITHOUT cloning RefStack
6) DEBUG mode using DEBUG env variable
7) Debug mode will map PWD to /dev to make code edits easier

TODO:
1) the command to start tempest is NOT working, needs to get fixed
