Gorka Eguileor bf23678fe0 Honor multipath config everywhere
There are multiple places in Cinder where the os-brick call to get the
connector properties is not passing the "multipath" and
"enforce_multipath" configuration options.

This means that some driver won't return a multipathed connection
information on the initialize_connection RPC call, resulting in a single
pathed attachment even when the os-brick connector is instantiated with
the right configuration option.

This patch fixes the different calls where this is an issue:

- Backup create
- Backup restore
- Kaminario create volume from snapshot
- Kaminario create volume from volume
- Volume rekeying

And also in places where this is not affecting operations because
drivers are always returning multipathed information:

- Unity driver
- IBM FlashSystem
