Lucas Alvares Gomes 3189c16a5e Fix waiting for target disk to appear

This patch is changing the _wait_for_disks() method behavior to wait to
a specific disk if any device hints is specified. There are cases where
the deployment might fail or succeed randomly depending on the order and
time that the disks shows up.

If no root device hints is specified, the method will just wait for any
suitable disk to show up, like before.

The _wait_for_disks call was made into a proper hardware manager method.
It is now also called each time the cached node is updated, not only
on start up. This is to ensure that we wait for the device, matching
root device hints (which are part of the node).

The loop was corrected to avoid redundant sleeps and warnings.

Finally, this patch adds more logging around detecting the root device.

     If root device hints are provided on the node, wait for the root device
     instead of the first disk. This fixes deployment when the target disk takes
     time to load.
