DietPi-Software | Bazarr: Add/Enhance Sonarr/Radarr/Plex integration

[MichaIng]

Currently we do not configure Bazarr with Plex automatically. This could be added, like we do for Sonarr and Radarr.

In case of Sonarr and Radarr, we check the used plain HTTP port and configure Bazarr to use that one. Better would be to check whether the HTTPS listener is enabled, in case check for the HTTPS port and use that one. This becomes mandatory once we implemented HTTPS OOTB with a self-signed cert or Let's Encrypt cert if present.
