Though still, how would the RA inform the tools about description &
defaults for this?
this is where i'm a bit lost... these aren't RA parameters so in
theory there's nothing to change right?
Ah, but they are. For example, the RAs currently use their metadata to
tell the GUI what defaults to set for clone_max, clone_node_max already,
and I'd expect that a drbd RA would also wish to tell us that yes, it
would want to have notifications enabled by default pretty please, and
that yes, it's a master-slave one. (Currently, this is indicated by the
promote/demote/notify ops being in the metadata.)
If we move it out of the regular namespace, it follows they shouldn't be
described within the regular <parameters> section in the metadata
either. So we need to put them somewhere else...
