Script to move geem_package docker contents between local hosts, and other things

[ivansg44]

@ddooley

scripts/geem_package_handler.py will allow us to backup, delete and insert geem_package contents from local docker containers using .tsv files. This will be a good way to manage data across local hosts during the development stage of this project. I have also included tests for this script.

Other small changes:

• Created a test docker-compose file for creating testing docker environments

• Created sys_admin and test_packages fixtures

• Added .idea/ to .gitignore

  • https://stackoverflow.com/a/17049458

  • A lot of people use JetBrains

sys-admin and package template fixtures have been added, and can be loaded the same way shared_packages is.
