mdadm: add retries as well as additional steps to stop arrays that may be resyncing

495. By Ryan Harper on 2017-05-03

clear-holders: mdadm use /proc/mdstat to wait for array to stop

shutdown_mdadm needs to wait until the md device has stopped. Using
files in sysfs is unreliable due to a kernel bug (LP:1682456) so instead
use device presence in /proc/mdstat.

Add the use of --manage flag to force mdadm to interrupt actions on the
device (like a resync).

Add vmtest with storage config to recreate issue (LP:1682584) found using
early_command to dirty existing disks with raid configurations.

Fixes: LP: #1672584

top-level 'network' key for cloud-init to detect network configuration.

Update vmtest and unittest to exercise network path.
