I want to initiate a discussion about different backend storage types for
Ceph. Now all types of drives (HDD, SAS, SSD) are treated the same way, so
the performance can vary widely.

It would be good to detect SSD drives and create separate Ceph pool for
them. From the user perspective, it should be able to select pool when
scheduling an instance (scenario for high-IOPS needed VM, like database).
