Summary row shows;
- osd count
- osd up count
- osd's down
- disk size summary (pie chart showing what sizes of disk are in the cluster
- table of osd to disk size
- OSD encryption summary (how many of my OSDs are encrypted?)
- OSD type status (how many OSDs are filestore vs bluestore

Panel includes an OSD id which is used as a filter for the filestore
performance row

The performance row now shows average OSD performance for a single OSD or
all OSDs. This can then be used for side-by-side comparison with OSD
performance across the cluster at the 95%ile.
