Jonathan Brassow 8615234c0f RAID: Fix bug making lvchange unable to change recovery rate for RAID
1) Since the min|maxrecoveryrate args are size_kb_ARGs and they
   are recorded (and sent to the kernel) in terms of kB/sec/disk,
   we must back out the factor multiple done by size_kb_arg.  This
   is already performed by 'lvcreate' for these arguments.
2) Allow all RAID types, not just RAID1, to change these values.
3) Add min|maxrecoveryrate_ARG to the list of 'update_partial_unsafe'
   commands so that lvchange will not complain about needing at
   least one of a certain set of arguments and failing.
4) Add tests that check that these values can be set via lvchange
   and lvcreate and that 'lvs' reports back the proper results.
