3PAR driver is populating the metadata field with unnecessary data.

[Kurt Martin]

Currently, both the HP 3par iSCSI and FC drivers are populating the volume and snapshot metadata field with unnecessary data that should actually be stored on the backend. This data should not be accessible by the user which is it today and could be updated as well.

    Remove unnecessary metadata from the 3PAR drivers

    Currently, both the HP 3PAR iSCSI and FC drivers are populating
    the volume and snapshot metadata field with unnecessary data that
    should actually be stored on the backend. This data should not be
    accessible by the user which it is today and could be updated as well.

    This patch will remove all custom 3PAR data from the metadata fields.
