Travis Nielsen 831c15086a ceph: support all layers of CRUSH map with node labels
The node labels were already supported for zones and regions to add to
the CRUSH map. Now all layers of the CRUSH map will be supported
with the new labels such as topology.rook.io/rack.
The labels will be detected at the osd startup time
similar to the zone and region labels already being detected.

Rohan CJ b16d55f4a0 Ceph: fix the deduplication of tolerations collected for the drain-canary
- Implement exportable TolerationSet with the following differences:
  - Change map key to a string to ensure it is deterministic.
    The old key was a struct that included a pointer.
  - Sort the outputted list by this key to ensure the order is deterministic.
  - Get the tolerations from the deployment instead of the pod as pod tolerations
    are sometimes modified by the system. We only want user provided tolerations
    in our deployment.
- Modify tests to try duplicate keys from different structs. The old way tested duplicate
  keys using the same structs.

Rohan CJ 17f6a25b2b Ceph: use the rook image for drain-canaries.
Change the canaries to use the rook image instead of the busybox image to
run `sleep infinity`. This removes our dependency on an external image that
we do not control.

Sébastien Han 05140d7a9e ceph: hide wrong error for clusterdisruption controller
The clusterdisruption starts up before the Ceph cluster is created and
during the initilization, it'll display invalid error messages such as:

2019-10-14T04:22:21.243679454Z 2019-10-14 04:22:21.243668 E | clusterdisruption-controller: could not check cluster health: failed to get status: exit status 1

That error message is invalid since the cluster is not up and running
YET.
So let's simply log a message.

Rohan CJ 195f20ad01 Pick up tolerations for drain canary pod from the osd.
This change is necessary drain canary pod needs to be schedulable on
the same nodes as the OSDs. Since it affects multiple OSDs, we need to
gather tolerations from multiple OSDs.

Ashish Ranjan c4ee336fe0 fix(fencing): change mdb controller to use namespace for checking status
This commit changed mdb controller to make use of cephCluster's namespace instead of cephCluster's name for checking the ceph health as the ceph config is located in the cephCluster's namespace folder which can makes mdb controller fail when rook operator is deployed in any other namespace apart from rook-ceph.
