If the ceph version does not suppport the exporter, the operator
will attempt to delete the service monitor related to the exporter
to ensure it does not exist for a node. If the expected rbac does
not exist, this will cause unnecessary errors since there would anyway
be no service monitor to delete. So we ignore the error of deleting
the service monitor for the exporter.
The context is also passed to the exporter so a new kubeconfig does
not need to be initiated and cause unnecessary logging about
invalid options for the config.

Cleanup exporter daemon even if ceph version is not supported along with other resources like
metrics service and service monitor.

When deploying a cluster with Helm Chart, if the namespace is not the default value `rook-ceph`, and if the monitoring feature is enabled, then the generated ServiceMonitor's `rook_cluster` selector now follows the namespace, not the hard-coded value `rook-ceph`.

The exporter is enabled by default, but the service monitor
can only be enabled if prometheus CRDs are available. The
monitoring.enabled must be set to true as the flag that
prometheus is available and the service monitor should
be created.

The prometheus mgr module and ceph exporter can now be optionally
disabled by the monitoring.metricsDisabled setting in the
CephCluster CR. These will not be disabled by default, rather
than the mgr module being disabled by default from v1.11.4.

The expected ceph version for exporter is changed temporarily because
some regression was detected in Ceph version 17.2.6.
Thus, disabling ceph-exporter for now until all the regression are fixed.

Remove the `ceph-conf-dir` volume and volume mount from exporter
as it's no more required to spin up exporter daemon

The exporter requires the mon config and keyring.
Use the CEPH_ARGS env var to specify the config
instead of expecting a ceph.conf to be generated
by another component on the host path.

ceph crash pod gets rook version label added unintentionally, which is only for deployment label.
changes include:
1, make a copy of the labels for pod spec from deployment labels just before adding rook version label.
2, add unit test to make sure it works as designed.
This fix along with pr 11674 is to stop ceph daemons pod restarting unnecessarily after upgrading rook operator.

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.
