minixjr (https://www.vdr-portal.de/forum/index.php?thread/131575-yavdr-ansible/&postID=1313526#post1313526).

TODOs:
 - seperate role(s) for vdr-plugin-epg2vdr and scraper2vdr
 - configure epg2vdr and scraper2vdr
 - allow to use a seperate MySQL/MariaDB server instead of a local one

+#The root SQL password is only stored (NONE), because the epgd-tool
+#is expecting it. But it is not really used,
