ceph-volume/ceph_volume/util: ceph-volume multi-actuator drive attribute

As storage capacities grow, multi-actuator technology introduced by Seagate addresses the downward pressure on performance that comes with growing drive capacities and areal densities. Having multiple actuators enables drives to maintain the performance needs of customers with data-intensive applications. However, this innovation requires storage stack changes because a single hard drive is now represented by two or more independent actuators (independent_access_ranges) that transfer data concurrently and are represented by a single LBA address space.

This code addition to the `ceph-volume` command assists Ceph administrators in identifying drives with multiple actuators by utilizing the Linux kernel's multi-actuator support introduced in version 5.16. Dual-actuator hard drives are gaining market share and becoming more important to Ceph deployments on large discs.

The code has been tested with Seagate Osprey Exos 2X18 with Mach.2 technology.
