Cactus comments (#2089)

* Add construct for cactus comments role

* Adjust config files

* Add docker self build to defaults

* Adjust tasks

* Fix smaller syntax errors

* Fix env argument

* Add tmp path to allow container writing there

Background why I did this: https://docs.gunicorn.org/en/stable/settings.html#worker-tmp-dir

* Change port back to 5000 as not configurable in container

* Try to add appservice config file for synapse to use

* Inject appservice file

* Correct copied variable name

* Comment out unused app service file injection

would need mounting the appservice file to the synapse container i guess

* Move role before synapse to be able to inject during runtime

* Remove unused parts

* Change default user id to mirror official docs

* Add docs

* Update roles/matrix-cactus-comments/tasks/setup_install.yml
