The operator settings loaded from the configmap have proven
inefficient for load time and frequently checking the configmap.
To avoid this ineffenciency, the configmap is only loaded once
each time it is created or updated. The values in the configmap
are applied as environment variables, which then are very efficient
to query throughout the various controllers, without needing
to be concerned about loading the configmap again.

Alerting on controller-runtime's workqueue_depth can be useful for
debugging controllers. Also having a prometheus target for a pod gives
another data point that the system is working as expected. It is useful
for uptime alerts.
Make the bind address configurable via the configmap while still retaining the default
behavior that it is disabled.

Adding CephCOSIDriver CRD and controller. The controller will bring up
the ceph cosi driver when first object store is created in the rook
operator namespace. Then admin can defined COSI CRDs like BucketClass
and BucketAccessClass for different object stores deployed via Rook.
Using the BucketClass and BucketAccessClass, user can define
BucketAccess for backend bucket in the RGW. The CephCOSIDriver CRD
defines configuration options for ceph cosi driver. In the first version
its usability is minimal. Even if it is not defined Rook will bring up
the ceph cosi driver with default values.

The machine disruption budgets for handling openshift
machines and machinesets are now removed since they
have been unused and unmaintained since implemented.
This feature is expected to be handled with the more
common Pod Disruption Budgets. A workaround is for the
cluster admin to set up their machine sets so they
match the zone topology. See the original design
doc from the feature here:

The crash collector controller is designed for watching nodes where
ceph daemons are running, and ensuring a special daemon is running
on that node to provide additional support for ceph on that node.
The crash collector is the first example of a daemon that should be
running on all the ceph daemon nodes. The next example of such a
node daemon will be the ceph exporter that will listen for the
ceph metrics as described in the design doc.
https://github.com/rook/rook/blob/master/design/ceph/ceph-exporter.md
Now the crash collector controller is renamed to the node daemon controller
so the ceph exporter daemon can also be managed by the same controller.

finally, admission controller will be enabled default
without any script/manual step. But it still requires cert-manager
to be installed which I believe is already installed in clusters.
**Note**
Code doesn't return error it just logs the error since
we don't want to stop reconciling if the admission controller fails.
We can work on this once the admission controller is stable.

This commit is a large refactor on how the operator starts, stops and
how it starts various sub-components such as the ceph-csi driver. It
also refines the way we cancel orchestrations. We don't use breakpoints
anymore but send our self a SIGUP to reload our controller runtime
manager.
The reload will happen under different circonstances like:
* a new adminission controller secret is created/deleted/changed
* a CephCluster CR is edited
As mentioned earlier, the csi driver now has its own controller, just
like flex. It reacts to change in the operator config map for particular
ROOK_CSI_ fields.
A second new controller for the operator's general config has been
created, it manages:
* the logging level
* the ceph CLI command timeout
* the discovery daemon
The operator reacts much more rapidly to cancellation events by stopping
the manager's context and reloading it.

Our admission webhooks will now run as part of the Operator container
and not an additional deployment. This has the advantage of consuming
fewer resources in the cluster and not having to manage affinities and
tolerations. This only drawback is that the Secret containing the
certificates is not mounted anymore and the content needs to be written
inside the Operator. This is not practical since we also need to watch
for the Secret content to change. Meaning that the certificates have
been renewed and the webhook server needs to use them.
A new approach is on its way to hopefully simplify this last issue and
implement a watcher for the Secret.
In the meantime, users need to use the cert-manager or renew
certificates manually. Additionally, they must update the
ValidatingWebhookConfiguration object with the new CA bundle.

This is the final conversion to controller-runtime conversion. This time the
CephCluster CRD has been converted to use the controller-runtime
library.
The controller incorporates all the previous watchers too, so the Node
and hot-plug configmap are been watched too.
Only the operator setting configmap is not being watcher since it's not
related to the CephCluster CRD.
Not only the patch converts to controller-runtime but also tries to
re-organize the tree of the repo to actually make the code more
readable and have better functions/methods/tests separations.

Now, the CephBlockPool CRD is managed with the controller-runtime.
So the watcher is outside of the main controller reconciliation loop of
CephCluster which brings numerous benefit such as:
* having its own reconciliation loop
* won't block anything from the main CephCluster controller loop
* fast than waiting for CephCluster loop to completion

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.

A new controller to bootstrap ceph-crash pod on Ceph nodes running Ceph
pods only.
This implementation is unfortunately a mix of 'hacks' to make the daemon
working correclty. The ceph-crash script faced different issues:
* it's not a daemon
* it does not have any key in cephx
* it runs ceph commands under the hood which need an admin key and a
ceph.conf
On upstream Ceph, ceph-crash needs to grow better, once that happens we
will improve our implementation.
This also enhances osd provisionConfig struct with DataPathMap
Pod volumes and volume mount needs DataPathMap to perform the right
actions on log and crash dir. Exposing DataPathMap makes that possible.
Obviously, this is exposing ceph crash reports on the host as
well as pushing them into the mgr.
Basically, if a daemon fails, it'll put its core dump into
/var/lib/ceph/crash, bindmounting this dir on the host, ensures that the
crashes don't get lost when the pod dies.
Example:
