 Conflicts:
	src/pybind/mgr/dashboard/frontend/src/app/ceph/cluster/osd/osd-list/osd-list.component.html
- Changes in the i18n section line 71 - 73
- Removed new lines of "ng template osdUsageTpl" which came with the cherry-pick
  since the template is already in a tab and thus would be duplicated
	src/pybind/mgr/dashboard/frontend/src/app/ceph/cluster/osd/osd-list/osd-list.component.ts
- Match angular 8 line 59 ("ViewChild")
