Allow specific GDP fusion backup storage classwith Qos to avoid filling production filesystem

See this idea on ideas.ibm.com

When doing fusion GDP backups to S3, fusion is doing a snapshot and then after a clone using mmxcp. This clone is then transferred to S3. When doing it on production systems, this clone is wasting space on production filesystem (i.e flash) as we need to "double" the capacity used to maintain the clone until it is transferred to S3.

We need a specific storage class so that this clone done  can be done over a specific "backup filesystem" ( i.e, not A/A, not flash, cheaper storage) and then transferred to S3 

This should also include QoS as well ( if not, 10 simultaneous backups can collapse the network as there is a high bandwidth) 

We suffered outages as generating multiple backups at the same time filled production filesystem stopping the whole cluster

    I merged your idea with SPFUS-I-91, since your problem should be solved by using shallow clones.
