Matthew Heler 4ad893eb1a Additional Ceph tunning parameters for openstack-helm
osd_scrub_load_threshold set to 10.0 (default 0.5)
 - With the number of multi-core processors nowadays, it's fairly
   typical to see systems over a load of 1.0. We need to adjust the
   scrub load threshold so that scrubbing runs as scheduled even
   when a node is moderately/lightly under load.

filestore_max_sync_interval set to 10s (default 5s)
 - Larger default journal sizes (>1GB) will not be effectively used
   unless the max sync interval time is increased for Filestore. The
   benefit of this change is increased performance especially around
   sequential write workloads.

mon_osd_down_out_interval set to 1800s (default 600s)
 - OSD PODs can take longer then several minutes to boot up. Mark
   an OSD as 'out' in the CRUSH map only after 15 minutes of being
   'down'.
