Update ceph nagios plugin
Changes ceph plugin so it ignores ceph rebalancing unless there is a large percentage of misplaced/degraded objects (return warning for that). Adds config options to tweak that monitoring, and also just warn if nodeep-scrub was deliberately set. Includes some basic unit tests. Change-Id: I317448cd769597068a706d3944d9d5419e0445c1
