[pve-devel] [PATCH manager] ui: add ceph recovery graph and progressbar

[Dominik Csapak]

shows a runningChart (like for reads) for the recovery speed
also shows a progressbar of the health percentage of the cluster
with an estimate of how long the recovery might need
(unhealthy objects) / (objects per second)

only show them when a recovery is ongoing or there are unhealthy
objects

we could also opt to only show it when there is really recovery
going on (recovering_objects_per_sec !== undefined) but
in my tests sometimes during recovery, ceph would not return those
values intermittently, making the panel flicker, so i opted
to show it also when there are unhealthy objects
(though i am not opposed to to the first and have some counter
to catch intermittent missing values)
