We need basic tests for the mediawiki-containers install process. Things that should be covered:

• Equivalent of curl | bash install
  • No git checkout in path.
  • Possibly: cat /path/to/mediawiki-containers/mediawiki-containers | sudo bash.
  • Will need to export settings / add support for skipping questions.
• Stop, start
• Run updater in /etc/cron.d/mediawiki-containers, assert that the wiki is still up.
