The 'force' parameter of os-brick's disconnect_volume() method allows
callers to ignore flushing errors and ensure that devices are being
removed from the host.
We should use force=True when we are going to delete an instance to
avoid leaving leftover devices connected to the compute host which
could then potentially be reused to map to volumes to an instance that
should not have access to those volumes.
We can use force=True even when disconnecting a volume that will not be
deleted on termination because os-brick will always attempt to flush
and disconnect gracefully before forcefully removing devices.

A recent thread in the mailing list [1] reminded me that we
don't have any documentation for the service user token feature
added back in ocata under blueprint use-service-tokens.
This change adds a troubleshooting entry for when using service
user tokens would be useful, and links to it from two known
trouble spots: live migration timeouts and creating images.

Import the user guide cli-use-snapshots-to-migrate-instances
available on the old openstack-manuals repository.
This user guide describe how to migrate an instance based on a cloud
to another.
It is updated with openstack cli commands.
