Script for Rebuilding Grader Base and Removing Linked Images

[williams-jack]

Feature/Problem Description

When changes have been made to the Worker logic, we need to rebuild the image for it, and then remove an images currently on the Orchestrator to force clients to rebuild their grader images given the new base image.

Solution (Changes Made)

• Script added that does the following:
  • Rebuilds the worker image.
  • Removes all .tgz files present in orchestrator/images.

Additional Notes:

To run the script, execute the following in the shell (from the project level):

$ cd orchestrator/scripts
$ ./rebuild-grader-base

Please make the relative paths less relative, so I can do cd orchestrator: ./scripts/rebuild.... as well as from within the scripts subdirectory, and this is good to go in
