Subject: [PATCH] mgr/dashboard: Automatically refresh the crush map metadata
 table

If we make any change to the osd crush map like do an osd crush reweight from cli, for that change to be reflected on metadata table we need to reload the entire page. Instead this PR takes care of auto refreshing the tree view.

Fixes: https://tracker.ceph.com/issues/48922
