Test deployment

[skuzzle]

Create a test deployment per issue-xx branch like:

• Parameterized docker file with
  • domain = issue.cmp.taddiken.net
  • separated mongo connection
  • less ram (bout 512 at max per system)
• We must build and publish the docker image per branch (currently happens only on master)
  • We must either NOT publish latest tag on feature branches OR modify the production deployment to use explicit versions rather than latest (would be cleaner anyways)
• Should set property for frontend to display a huge This is a test system warning
• GitHub action should trigger the deployment upon building the branch
• GitHub action should trigger the removal of the deployment upon branch deletion
