This commit adds context parameter to utilities in opcontroller to
remove context.TODO use in opcontroller. By this, we can handle
cancellation of reconcilers in a fine-grained way.

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.

If the cluster is external we want to periodically rehydrate the mgr
endpoint. This handles the scenarion where the active manager changes,
so we need to update the endpoint with the new IP address.
The create-external-cluster-resources.py script now requires an extra
permission to query the manager service so Rook can discover the active
one and its IP.
Testing:
```

Because of the recent CRD changes made, the mon count had a minimum of
1, making the configuration of the external cluster impossible. The
operator would fail to add the finalizer:
```
2021-04-29 16:57:38.429451 E | ceph-cluster-controller: failed to reconcile. failed to add finalizer: failed to add finalizer "cephcluster.ceph.rook.io" on "test-external": CephCluster.ceph.rook.io "test-external" is invalid: spec.mon.count: Invalid value: 0: spec.mon.count in body should be greater than or equal to 1
```
We now fixed the CRD as well as adding the CR status.

It's better to validate ownerReferences when setting them. In addition, we should use
controllerrutil.Set{Controller,Owner}Reference, that have such validation, as possible.

The active mgr should match the labels on the services that
are available for prometheus and the dashboard. The selector
labels must be updated whenever there is a new active mgr.

The conditions on the cephcluster CR were being set to false
when not in progress, which is misleading to the purpose of
conditions. The conditions will now always represent current
state of the cluster. Transient conditions that show progress of
a reconcile will be removed from the status.

When the cluster is external we want to expose manager service port
along with the endpoints.
This allows us to connect but Rook will keep on using 9283 as a facing
port for Prometheus and more.
```
monitoring:
enabled: true
...
...
externalMgrPrometheusPort: 9283

Since we moved to the controller-runtime, events are processed one by
one and so are reconciles. This means we won't have multiple
orchestrations happening at the same time. Thus removing this code.
Also removing one unused variable.

We only need to read the ceph cluster version if the cluster external
has external monitoring enabled.
This avoids any issue during upgrades from 1.3 to 1.4 when monitoring is
enabled and ceph caps have not been updated.

Instead of setting the Phase of the CR once the reconcile is done, let's
actually set in from the healthcheck so it is more accurate.

We can now connect an external prometheus exporter to Rook to collect
metrics and generate alerts from Prometheus.
Just enable this in the CephCluster CR:
```
spec:
external:
enable: true
monitoring:
enabled: true
rulesNamespace: rook-ceph
externalMgrEndpoints:
- ip: 192.168.39.182

To provide more context for executing commands in a ceph cluster,
the full clusterInfo is now passed to the ceph execution commands.
All information about the cluster will now be available throughout
all the areas of the operator. The namespace, ceph credentials,
mon endpoints, and other info is a core part of that cluster info.
Arguments passed through the controllers are also simplified for
mons, mgr, osds, and other daemons where the parameters had
become too complex.

The operator should only connect to ceph with a single set of creds.
In a converged cluster this will be the admin creds and in an external
cluster it will be lower-privileged creds. Independent clusters were
implemented with a separate set of creds. To simplify the code these
are now merged to a single set.

If the admin key is available, set the external creds struct
to use that admin username and key instead of requiring the
callers to check every time if they should use the admin
key or the external key.

During cluster deletion, we currently only retry for a couple minutes
to wait for the pvcs to be deleted. After the timeout, we proceed
with the cluster deletion. To properly protect the pvcs for proper
cleanup, the finalizer should not be removed until the pvcs
are all confirmed to be deleted. In order to not block other cluster
events, we re-queue the deletion event to run again every 10s
until the pvcs are deleted or the finalizer is manually removed.

When Rook-Ceph is connected to an external cluster and the admin tries
to create resources such as CephFilesystem or CephObjectStore, we must
create the rook-ceph-config secret so that the daemons can get their mon
information.

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.
