Bug Description

VNX driver are leveraging LUN migration functionality when clone/migrate/retype volume.
The migration rate is set to 'high' by hard code.

VNX needs to allow admin to control the migration rate by adding volume metadata before triggering any operations involving LUN migration.

The required metadata key is 'migrate_rate', available metadata value is 'high', 'asap', 'low' and 'medium'

Thanks
Peter

    VNX: Allow set migrate rate when migrating volumes

    VNX driver is leveraging LUN migration functionality when
    clone/migrate/retype volume. The migration rate is set to 'high'
    by hard code.

    This patch will allow admin to control the migration rate by
    adding volume metadata before triggering any operations involving
    LUN migration.

    The required metadata key is 'migrate_rate', available metadata
    values are 'high', 'asap', 'low' and 'medium'.
