Use LVM RAID instead of LVM of top of MD RAID in the Anaconda installer.
== Detailed Description ==
In the current situation when a user chooses LVM (or Thin LVM)
partitioning in the Custom Spoke and then sets RAID level for the VG
Anaconda (and Blivet) create an MD RAID device which is used as a PV
for the VG. With this change we are going to use LVM RAID directly
instead. That means that all the LVs in that VG will be RAID LVs with
the specified RAID level. LVM RAID provides same functionality as MD
RAID (it shares the same kernel code) with better flexibility and
additional features expected in future.
I'd like to see (a link to) a more comprehensive discussion of the
purported advantages of LVM RAID over LVM on MD RAID here.
