Bug description:
OS-Brick disconnect_volume code assumes that the use_multipath
parameter that is used to instantiate the connector has the same value
than the connector that was used on the original connect_volume call.
Unfortunately this is not necessarily true, because Nova can attach a
volume, then its multipath configuration can be enabled or disabled,
and then a detach can be issued.
This leads to a series of serious issues such as:
- Not flushing the single path on disconnect_volume (possible data loss) and leaving it as a leftover device on the host when Nova calls terminate-connection on Cinder.
- Not flushing the multipath device (possible data loss) and leaving it as a lefover device similarly to the other case.
