Update volume statistics.

Three kinds of data are stored on the Synology backend pool: 1. Thin volumes (LUNs on the pool), 2. Thick volumes (LUNs on the pool), 3. Other user data.

other_user_data_gb is the size of the 3rd one. lun_provisioned_gb is the summation of all thin/thick volume provisioned size.

Only thin type is available for Cinder volumes.
