Jonathan Brassow 2691f1d764 RAID: Make RAID single-machine-exclusive capable in a cluster
Creation, deletion, [de]activation, repair, conversion, scrubbing
and changing operations are all now available for RAID LVs in a
cluster - provided that they are activated exclusively.

The code has been changed to ensure that no LV or sub-LV activation
is attempted cluster-wide.  This includes the often overlooked
operations of activating metadata areas for the brief time it takes
to clear them.  Additionally, some 'resume_lv' operations were
replaced with 'activate_lv_excl_local' when sub-LVs were promoted
to top-level LVs for removal, clearing or extraction.  This was
necessary because it forces the appropriate renaming actions the
occur via resume in the single-machine case, but won't happen in
a cluster due to the necessity of acquiring a lock first.

The *raid* tests have been updated to allow testing in a cluster.
For the most part, this meant creating devices with '-aey' if they
were to be converted to RAID.  (RAID requires the converting LV to
be EX because it is a condition of activation for the RAID LV in
a cluster.)
