Clarify risks of not using shared storage
Make it clearer what the risks of not using shared storage are. Information is based on: http://docs.openstack.org/user-guide-admin/cli_nova_evacuate.html which says "The command rebuilds the instance from the original image or volume" but later says that "To preserve the user disk data on the evacuated server, deploy Compute with a shared file system" and then use --on-shared-storage.

Disable shared storage recovery for instances. Use at your own risk!

Indicate that nova storage for instances is not shared across compute

|
nodes. This must match the reality of how nova storage is configured!

Otherwise VMs could end up in error state upon evacuation. When

storage is non-shared, instances on dead hypervisors will be rebuilt

|
from their original image or volume, so anything on ephemeral storage
|

will be lost.
