If the cmd-reporter key is set under the resources
element in the CephCluster CR, the memory and cpu request
and limits will be set on the ceph detect version job
and network job accordingly.

Resolves CIS benchmark rule 5.7.3, Pods part. SecurityContext
should be explicitly defined in pod level of Pod spec section.
It is sufficient to specify empty securityContext to satisfy
CIS 5.7.3 rule.
5.7.3 Apply Security Context to Your Pods and Containers
When designing your containers and pods, make sure
that you configure the security context for your pods,
containers, and volumes.

This new setting is of Boolean type and defaults to "false".
When set to "true", it changes the behavior of the
rook operator to
nable host network on all pods created by the cephcluster controller
new method to check the setting: opcontroller.EnForceHostNetwork()

Change how Rook detects network CIDRs for Multus networks. The IPAM
configuration is only defined as an arbitrary string JSON blob with a
"type" field and nothing more. Rook's detection of CIDRs for whereabouts
had already grown out of date since the initial implementation.
Additionally, Rook did not support DHCP IPAM, which is a reasonable
choice for users. And more, Rook did not support CNI plugin chaining,
which further complicates NADs. Based on the CNI spec, network chaning
can result in any changes to network CIDRs from the first-given plugin.
All these problems make it more and more difficult for Rook to support
Multus by inspecting the NAD itself to predict network CIDRs. Instead,
it is better for Rook to treat the CNI process as a black box. To
preserve legacy functionality of auto-detecting networks and to make
that as robust as possible, change to a canary-style architecture like
that used for Ceph mons, from which Rook will detect the network CIDRs
if possible.
Also allow users to specify overrides for CIDR ranges. This allows Rook
to still support esoteric and unexpected NAD or network configurations
where a CIDR range is not detectable or where the range detected would
be incomplete. Because it may be impossible for Rook to understand the
network CIDRs wholistically while residing only on a portion of the
network, this feature should have been present from Multus's inception.
Improving CIDR auto-detection and allowing users to specify overrides
for auto-detected CIDRs rounds out Rook's Multus support for CephCluster
(core/RADOS) installations. No further architectural changes should be
needed for CephClusters as regards application of public/cluster network
CIDRs for Multus networks.

Introduce a new env variable ROOK_CSI_IMAGE_PULL_POLICY in rook operator configmap which should be used to
customize the imagePullPolicy for the csi driver and imagePullPolicy property in cephVersionSpec for ceph pods.

This commit adds context parameter to k8sutil configMap functions. By
this, we can handle cancellation during API call of configMap resource.

We don't need to use tini.
We don't have anything in the rook operator that would
either create zombie processes (no threads) or use
exec (to fork). The Go binary has a really good
signal handling mechanism.

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.

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 app name was not being set in k8sutil's cmdreporter code, resulting
in jobs being labeled `app=` with no name. Change cmdreporter's `New`
method to validate the contents of the config struct and not the inputs
to the `New` method to help prevent an issue like this from creeping up
in the future.

Add a wrapper for the cmd-reporter function of the 'rook' binary to
k8sutil so that it's easier for operators to use the functionality.
Operators still need to have some idea of how CmdReporter works. It runs
the requested command in a job, but if the calling operator needs the
job to have special configuration, the operator must request the pointer
to the job struct from CmdReporter to modify it before calling the
CmdReporter's Run method.
