[pve-devel] [PATCH manager] ceph osd: ui: show PGs per OSD

[Aaron Lauterer <a.lauterer@proxmox.com>]

By switching from 'ceph osd tree' to the 'ceph osd df tree' mon API
equivalent , we get the same data structure with more information per
OSD. One of them is the number of PGs stored on that OSD.

The number of PGs per OSD is an important number, for example when
trying to figure out why the performance is not as good as expected.
Therefore, adding it to the OSD overview visible by default should
reduce the number of times, one needs to access the CLI.
