Add concrete season selection, narrow rootFolder names, notify admin in different chat and add requester user tag to sonarr/radarr

[anast20sm]

I add some functions that are useful in my case, where each user can add series/movies on their own chat, I track in a separated channel what is done and I add the tags in order to configure sonarr/radarr/tautulli notifications.

• Select multiple seasons and then send
• Narrow root folder names to the folder name instead of full path (in my case some of them are too long). Can be enabled in config
• Notify admin into a separate channel/group/chat by providing id in the config
• Add tag from who requests the movie/series. Tag must be already created in sonarr/radarr (#TODO create if new user) (in my case i use this to configure notifications for each user in sonarr/radarr)

I think these issues can be closed:
#116
#113
Not #84 but the notifications added could help if this is the requirement

PS: I do not have docker build knowledge by now, can someone build the image for me please ? :)

Thank you for the pull request and the additions that you made! These are a lot of improvements.

What do you think about making the selection of the seasons a bit more fluent by adding a button to directly select all the current and future seasons with one press?

I was also thinking about adding some explanation about the new settings in the config_example.yaml-file. I don't think the new settings are so self-explanatory.

I've tried building the new Docker image and it builds without problem.
