Enable Deduplication Determined by Performance Policy

When creating or editing a pool, use the --dedupe_all_volumes no option to disable deduplication by default on all newly created volumes. Note that existing volumes are not affected.

When set to no, the deduplication setting for the volume is inherited from the pool's performance policy. When new volumes are created, they inherit the deduplication setting defined in the performance policy. Deduplication on existing volumes can be changed by editing the volume attributes.
