commands: rename "osdlevel" option and property, make it a choice

Rename both the option and property to "osd-level", which fits a bit
better with the general naming scheme. Make it a choice instead of an
integer range. I failed to come up with good names for the various
levels, so leave them as-is.

Remove the useless property handler for the "loop" property too.
