Improve 'mo' script. #126
Description
The mo script could use a couple improvements:
- It's written in Bash, so it won't work on Windows.
- The URLs to which it makes requests are derived from the json file's path. Since configurations was moved into the mongo_orchestration package, it can't be run anymore from the root of the project. Specifying the absolute path to the json file to use shouldn't break the script.
