Matthew Heler fc76091261 [CEPH] Fixes for the OSD defrag cronjob
Fix a naming issue with the cronjob's binary, and schedule the cron
job to run every 15 minutes for the gates. Additonally check to
to ensure we are only running on block devices. Also update the
script to work with ceph-volume created devices.
