Bug description:
  [Impact]
  system does not boot after converting lvm volume to raid1 w/o having mdadm installed.

  [Test case]

  1. Install server with subiquity to VM
  2. Add second disk to it
  3. Run pvcreate /dev/vdb
  4. Run vgextend ubuntu-vg /dev/vdb
  5. Run lvconvert -m1 --type raid1 ubuntu-vg/lv

  Reboot and check that it still boots.

  [Regression potential]
  Not really anything, we just add the raid1 module to initramfs, so it might be loaded during boot, and raid1 logical volumes might appear earlier.

  [Original bug report]
  After upgrading to Wily, raid1 LVs don't activate during the initrd phase. Since the root LV is also RAID1-mirrored, the system doesn't boot.

  I get the following message each time LVM tries to activate a raid1 LV:
  md: personality for level 1 is not loaded!

  Everything was fine with Vivid. I had to downgrade to Vivid kernel
  (3.19.0-30) to get my system to a usable state. I pretty much hope it
  to be a temporary workaround and I'll get the new 4.2.0 kernel work
  with Wily in days.
