It is impossible to create Manila snapshots after active controller was changed
Issue
After active controller node is restarted cluster will migrate manila-share to another controller. As a result, existing shares will contain "host" parameter that is not accurate for existing state of the cluster.
In my case this issue made it impossible to create snapshots for shares with outdated "host" parameter. But this situation may break another feature.
