Rohan CJ eaab7b161d Ceph: Info log significant events in the nodedrain controller.
Info log events where a drain canary is either scheduled on a new node
or removed from a node.

Rohan CJ 9d1419864e Ceph: Improve detection of stale canaries.
In the case where the node disappears abrubtly,
there was nothing to trigger the nodedrain reconciler to clean up
the stale canary.

Sébastien Han ad95c7296f ceph: do not print extended format for loggers.
When using the "errors" package, using `%+v` (extended format),
each Frame of the error's StackTrace will be printed in detail.
Let's only print `%v` to print the error.
If the error has a Cause it will be printed recursively.

Basically `%+v` has been replaced with `%v` for all `error` type
interfaces, whether the logger is Info, Warning or Error.

Sébastien Han 5ce2ed220e ceph: use "github.com/pkg/errors"
We now use the error package.
Kubernetes errors have been renamed kerrors since they are lower than
'errors'.

Rohan CJ 1ba2633c27 Ceph: Clean up canaries on nodes that no longer have OSDs or when the node is deleted.
This prevents long-lasting false positives that prevent the ordered progression
of drains.

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.

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.
