Alexander Deiter 907550015e Fix Infinidat driver to backup attached volume

For some historical reason, the Infinidat Cinder driver does not
allow to backup an attached volume. This makes it impossible to
create a backup for most use cases. As a possible solution we can
create and use snapshots as a backup source.

This patch implements attach/detach for snapshots and the ability
to use snapshots to perform non-disruptive backups.

Added functions:
* initialize_connection_snapshot()
* terminate_connection_snapshot()
* create_export_snapshot()
* remove_export_snapshot()
* backup_use_temp_snapshot()

And changed functions:
* create_volume_from_snapshot()
* create_cloned_volume()

remove the duplicated code and use the temporary snapshot
as the source for creating the cloned volume.
