Set up CT log test server and document it in Confluence.
The are (at least) two CT log implementations:
- The old CT log server. We have built an old version of it and attached it here:
ECA-3416. Will probably not work on modern Linux distributions without rebuilding or adding in the required (old) libraries.
- Trillian https://github.com/google/trillian
- There seems to be a dockerhub image for Trillian: https://hub.docker.com/r/letsencrypt/trillian_log_server
