Fix the issue when using with external ceph cluster, ceph exporter
secret isn't created which cause ceph-exporter fail to run. By
default this option is false means ceph-exporter will run for
external cluster.

metricsDisabled: false
This patch also adds metricsDisabled option to helm values.yaml.

The CreateOrLoadClusterInfo (and therefore LoadClusterInfo) methods were
not loading the ClusterInfo.OwnerInfo. This should help future CRD
controllers get the full ClusterInfo struct without having missing
information. Current controllers that need ClusterInfo fill the field
themselves.
During testing, I observed one corner case where an upgraded cluster was
missing the `rook-ceph-csi-config` configmap. The cluster had a
CephFilesystemSubVolumeGroup resource created, and the reconcile for
that resource was attempting to create the missing CSI configmap and
failing with a nil pointer exception due to the missing OwnerInfo field
in ClusterInfo. This cluster condition hasn't been reproduced in healthy
environments, and it is unknown how the CSI configmap came to be
missing. However, the case did expose the missing loaded info as a
potential for causing nil pointer exceptions during corner cases when
code is otherwise correct.

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had already grown out of date since the initial implementation.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.

few functions got change as they were deprecated
for ex: ioutil.Readfile change to os.Readfile
ioutil.TempFile change to os.CreateTemp
And fixed golang-ci-lint-issues

if Multus is enabled the clusterinfo should be updated with
network as multus as to run the ceph cmds in remote
executor

The CSI package needs to load clusterInfo, today this code is in the mon
package which makes the call of LoadClusterInfo impossible without
having a circular import.
