Mohammed Naser 29d2090aef Add throughput limits that scale per-GB
This allows new values in QoS specs:
 - read_bytes_sec_per_gb
 - write_bytes_sec_per_gb
 - total_bytes_sec_per_gb

The bytes value specifed in the QoS spec is multiplied
by the size of the volume in initialize_connection,
and the result is passed along like a standard <x>_bytes_sec
QoS value.
