Rename <mp3-metadata-interval> for clarity
Currently we have a mount specific config parameter called
mp3-metadata-interval, which sets the metadata interval for ICY metadata, used for MP3 or AAC (and maybe some other formats). Therefore the name is misleading, especially for users that stream AAC.
I would like to propose renaming it to
icy-metadata-interval for clarity that this affects ICY and not just mp3.
