Added mdadm assemble module function
Added mdadm assemble handling to the mdadm state
Fixed how I was interpreting the return status of mdadm -E with cmd.run
Fixed bug where raid.save_config would break if mdadm.conf weren't present
lvresize initial commit
mdadm -E is checked with cmd.retcode instead and we now check if devices are a
mix of RAID and non-RAID
This fixes a bad data output when prereq prerequireds break

Fix #15463 Fix #15331
Add __run_num__ and __sls__ to prereq failure condition

In addition add some comments to hopefully explain what we are doing
raid.assemble tells you which devices are RAID-ready and which aren't
Fixed a name reference in raid.assemble. Also, raid.assemble sorts the devices
alphabetically if it needs to report that the RAID and non-RAID devices are
mixed
use izip instead of izip_longest
You can pass raid.assemble a comma-separated list of devices now
Resolve issue #15532 set metadata to mdadm
removed unnecessary import
