In Rook v1.8 the min version of K8s supported is updated to 1.16.
Users running on older versions of K8s are recommended to update
to 1.16 or newer before updating to Rook v1.8.

With the release of Ceph CSI 3.4.0, Ceph CSI project came up
with a new support policy where we support only versions >= 3.3.0
The supported window of Ceph CSI versions is known as "N.(x-1)":
(N (Latest major release) . (x (Latest minor release) - 1)).
For example, if Ceph CSI latest major version is 3.4.0 today,
support is provided for the versions above 3.3.0.
If users are running an unsupported Ceph CSI version, they will be
asked to upgrade when requesting support for the cluster.
This PR lift the minimum supported version of Ceph CSI to 3.3.0
in this repo.

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.

During disaster recovery/migration of a cluster, as part of the failover, the
kubernetes artifacts like deployment, PVC, PV, etc will be restored to a new
cluster by the admin. Even if the kubernetes objects are restored the
corresponding RBD/CephFS subvolume cannot be retrieved during CSI operations as
the clusterID and poolID are not the same in both clusters
This PR creates a mapping between Cluster ID and RBD Pool ID between
local cluster and peer cluster.

Thanks to Golang 1.16, we can now embed files in the Go binary. This
means we don't need to add the CSI templates files to the container
image. They are added in the Go binary at build time.
The existing location of the template must be in the package calling it.
So they moved to pkg/operator/ceph/csi/template. All the files have been
symlinked back to cluster/examples/kubernetes/ceph/csi/template.

The `None` value Indicates that volumes will be mounted
with no modifications, as the CSI volume driver does not
support these operations. While volumes are provisioned
by the CephFS CSI driver the global permissions are set
on the volume and we dont expect the Fsgroup policy or
check from CO side to play a role here.
Ref #ceph/ceph-csi/../internal/cephfs/nodeserver.go#L190
```
!csicommon.MountOptionContains(fuseMountOptions, readOnly) {
// #nosec - allow anyone to write inside the stagingtarget path
err = os.Chmod(stagingTargetPath, 0o777)
```
The current default value ie `ReadWriteOnceWithFSType` cause
volumes to be examined to determine if volume ownership and permissions
should be modified to match the pod's security policy. Changes could occur
if the fsType is defined and the persistent volume's accessModes contains
ReadWriteOnce.

The rook.io/v1 package was only an internal implementation detail and
does not have any CRDs that rely on it. The CRD deserialization should
handle the change in internal types without any issue. This separation
gives more flexibility for the storage providers to implement exactly
what is needed for their storage provider instead of forcing to use the
same types and risk affecting another storage provider.

The GRPC metrics exposed by both the provisioner pod
and the node plugin pod on some port. Provisioner pod
is running on the pod network and the daemonset pods
run on the host network. sometimes starting the GRPC
metrics by default can lead to node plugin pods
crashloopback state this is due to the port conflict.
Moreover, the GRPC metrics are not for the user it's
for the one which will help to debug the time taken
by cephcsi to serve each GRPC call. Enabling it by
default won't be a good idea. So the plan is to
disable it by default, If someone faces any issue it
can be enabled later at some point in time.

If the kernel doesnt support mapping of
rbd image with deep-flatten feature,cephcsi
need to flatten the rbd image first and than
map the image on the node.
cephcsi first tries to add a task to flatten
the rbd image if its receives any permission
error it will try to call rbd CLI command which
is a blocking call.
This commit adds mgr caps to the csi-rbd-node user
so that cephcsi will add flatten task and return
immediate error to the kubelet, let kubelet retry
again,If we go with blocking rbd CLI call we may
end up having stale maps on the node in corner cases.
