Horizon doesn't have option of "in-use" Cinder volume backup

[Anusha chaparala]

Created 3PAR volume and launched KVM/hLinux instance, attached volume to the instance.
Tried taking backup of "in-use" volume where option is not available.Attached screenshot for reference.
Observed in Openstack version : Mitaka

When cinder volume backup was introduced, it was only supported for "available" volumes, which is what is reflected in Horizon. Backing up "in-use" volumes has been added to cinder and should be added to horizon

    Enable backups on in-use volumes

    In addition to "available" volumes, those that are "in-use" can now be
    backed up. Backing up "in-use" volumes requires setting the "force"
    parameter in the cinder backup call.
