Peter Rajnoha cba6186325 cmirror: check for cmirror availability during cluster mirror creation and activation 
When creating/activating clustered mirrors, we should have cmirrord
available and running. If it's not, we ended up with rather cryptic
errors like:

$ lvcreate -l1 -m1 --type mirror vg
  Error locking on node 1: device-mapper: reload ioctl on  failed: Invalid argument
  Failed to activate new LV.

$ vgchange -ay vg
  Error locking on node node 1: device-mapper: reload ioctl on failed: Invalid argument

This patch adds check for cmirror availability and it errors out
properly, also giving a more precise error messge so users are able
to identify the source of the problem easily:

$ lvcreate -l1 -m1 --type mirror vg
  Shared cluster mirrors are not available.

$ vgchange -ay vg
  Error locking on node 1: Shared cluster mirrors are not available.

Exclusively activated cluster mirror LVs are OK even without cmirrord:

$ vgchange -aey vg
  1 logical volume(s) in volume group "vg" now active
