Move /var/docker/image/bin scripts to git

We have a variety of useful helper scripts such as restoreunstable, logging output, etc. Right now, we just manually copy these between the machines, which is error prone, and we don't have versioning.

Task is to decide where these should go in git. If generic enough (and I think most are?) I'm thinking a scripts directory in IMAGE-server repo. I'm open to the argument they should be in the test repo, but I think these will be of use to others working on their own IMAGE server.

• Need approval from @jaydeepsingh25 @JRegimbal on location of these scripts (IMAGE-test, IMAGE-server, or another suggestion?)
• Ensure there are no API keys, etc. in any of the scripts. move any needed into .env files or however
• Ensure there are no unicorn/pegasus specific things that need to be generalized
• rework cron links, etc. to point to new location

I'd be fine with a scripts directory within IMAGE-server if you can really see other groups having a reason to use them!
