Simplified Script Warning

[cdunbar13]

Stage 1 of the script warning. Adds simple warnings when startup scripts start and end, and warning to terminal when users log in, letting them know that there the system uses startup scripts for configuration and how to check if they're still running.

Looks good, although I think we need some changes primarily in the text away from "it's unsafe" to a more strictly factual "services are (not yet) running". We anticipate replacing the prompt message soon with a 2nd PR, but it's better to assume it will be in the next release or two. So we should get it accurate across our array of operating systems.

For future record, I am testing with this blueprint for vm-instance behavior and behavior when wrapped with Slurm startup scripts:
