Find already existing or create new CKAN Docker images

• CKAN quick test to consider add or not to the stack #8
• Mentioned Official images (we may not able to use these)

  • https://docs.ckan.org/en/2.8/maintaining/installing/install-from-docker-compose.html

This is the current docker-compose.yml file we're using to test. They are using the https://hub.docker.com/u/ckan oficial imagens, but the official images don't have taged releases (just latest and, one docker dev-v2.6) and the latest seems to be using the master branch (unstable). Also the documentation related to docker seems to suggest fork the entire https://github.com/ckan/ckan/ and build the docker images as need.

This issue is to try find images that we could do the #8, even if it means create ourselves, like the https://github.com/covid-taskforce-cplp/hxldash-docker.

If this takes too much time we may abort.
