[Bug 1000710] [NEW] Attaching volume during instance boot doesn't work

[Martin Packman]

Public bug reported:

Using the newly enabled volume support on canonistack, it arrived at a
state where the volume believed it was in-use by the instance, but the
instance had not registered it. The volume then refused to be detached
from the instance, the command succeeded but no change occurred.

The sequence of events was:
* Start instance
* Create volume
* Wait till instance was listed as ACTIVE
* Attach volume
* SSH to instance... fails, instance not yet booted enough
* Wait more
* SSH to instance
* dmesg contains nothing about volume

The suggestion is the attach happened to soon in the boot process.

To recover, did:
* Reboot instance
* Wait till instance is listed as ACTIVE and can SSH to it
* Volume is now back to being available
* Attach volume
* dmesg contains information about the new volume
