Added an `add_dependencies` plugin to the Sphinx build process that parses the manifest files of the scanned backends and plugins and automatically generates the documentation for the required dependencies and triggered events. This means that those dependencies are no longer required to be listed in the docstring of the class itself. Also in this commit: - Black/LINT for some integrations that hadn't been touched in a long time. - Deleted some leftovers from previous refactors (deprecated `backend.mqtt`, `backend.zwave.mqtt`, `backend.http.request.rss`). - Deleted deprecated `inotify` backend - replaced by `file.monitor` (see #289).
