Use SSD disk for journal device

Try to find out if device is SSD disk, and use it for journal device


https://github.com/crowbar/barclamp-deployer/pull/211 is required
I think more like
``if node["ceph"]["osd"]["journal_devices"].include?(d.name) ||
(node[:block_device][dev_name]["rotational"] == "0" &&
 node["ceph"]["osd"]["use_ssd_for_journal"])```
