This commit adds new CSIDriverOptions section in
cephCluster CR. This section contains settings
for read affinity and kernel+fuse Mount options
These settings will be injected directly into
rook-ceph-csi-config cm to be applicable per
ceph cluster.

During certain maintenance tasks the admin will own running
operations on the ceph mgr, rgw, mds and rbd-mirror daemons
and the operator should not interfere with those operations.

Use K8s LivenessProbe mechanism to check OK-status of nfs-ganesha
container. A user may define his own lineness-probe, or a default one
which expects NFS TCP-port 2049 to be active; that is, willing to accept
new connections: for Ceph>=18.2.1 issue 'rpcinfo' call on local pod;
otherwise use standard K8s TCP-socket liveness probe mechanism.
Define permissive values to liveness-probe to ensure that the NFS
service is defined in failed-state only when it has non-recoverable
error.
The current default definition of LivenessProbe is expected to guard the
nfs pod from at least the following two cases:
- Deadlocks: where an nfs-ganesha server is running, but unable serve
new connections due to internal bad-state.
- Resource exhaustion on the host node (e.g. OOM) which prevents the
server from accepting new connections and reply to NULL RPC request.
In both cases we expect K8s to reschedule the nfs pod, most likely on
different host node.

Use the Rook image (defined by the operator pod) to detect the Multus
network address ranges. It is reasonable for users to want to have a
minimal Ceph image that does not have the `ip` utility installed, which
is used for detecting the address ranges of multus interfaces. Instead,
use the Rook image, which Rook can ensure has the `ip` tool if Ceph ever
removes it from their image.

When OSDs flap, ceph stops the OSD daemon if its marked down greater than
5 times in 600 seconds. But OSD pod restarts and marks the OSD `up` again.
This causes the PGs mapped to these OSDs to peer. While the PGs are peering,
IO to these PGs are blocked.
So we need to ensure that if ceph is marking OSD `down` due to flapping, OSD pod
should not restart to mark the OSDs `up` again.
This PR adds a sleep to the OSD pod if the container returned with a 0 exit code
Default behavior is to sleep for 6 hrs. But user can configure it from the
ceph cluster spec.

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.

This fixes the the MultiClusterDeploySuite CI failure. The operator
is timing out waiting for the mgr deployments to be
ready, according to the WaitForDeploymentToStart() method. After
the reconcile times out after about five minutes, the next
reconcile succeeds since the wait is only done for new mgr
deployments.

The idea behind this change is to use the readiness probe to implement
the mgr HA mechanism. In the current ceph mgr implementation only the
active instance offers the command 'mgr_status' through the admin
socket. We use this command combined with a Readiness Exec Probe to
detect which manager is active. Kubernetes will automatically mark
it as ready and redirect any service traffic to the active instance.

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.

The mons that are out of quorum may cause ceph commands to timeout
or fail unnecessarily trying to connect to a mon that is no longer
online. Now the mon health check will update the mon endpoints configmap
when a mon is detected out of quorum. This also means that if the
operator is restarted during a mon failover, the failed mon will no
longer remain in the ceph.conf, thus allowing the quorum to be more
likely to respond to the mons that are still in quorum.
The update for mons out of quorum only applies if other mons are in
quorum. If quorum is down, the configmap will not keep track of the offline
mons since too many are offline.

in case the OSD is taking some time to start. The OSD may be self-optimizing,

to retry for two hours in case the OSD is performing those operations.
