Changed some docker images to save space and added nzbhydra2 + radarr

Like promissed on reddit, here are my changes. If you use hotio/suitarr it downloads only one image and builds the different services on top on it.

I also added nzbhydra, an meta search for nzb indexers, here you add all your indexers and only need to add nzbhydra to sonarr/radarr/couchpotato

Also added radarr, my favorite for movies (replacement for couchpotato), it is an fork from sonarr.

Everything is commented out so you can decide if you want to add it or not
