The storage class already takes MountOptions(MountFlags), these are the
bind mount options. Some of these options may not be recognised by the
cephfs mount. Hence added a new parameterin Storage Class for
- cephfs kernel mount options,
- ceph-fuse mount options
Ceph kernel mount options are different from ceph-fuse options, hence
added two different parameters.

Ceph kernel client is more performant than ceph fuse client.
The kernel client has Quota support only in the kernel version >=4.17.
Hence use ceph kernel client when the kernel version is >=4.17.

When people have reviewed a PR, and the contributor updates it, the
reviews are staying valid. This is unfortunate as the PR might need new
corrections.
Ideally a positive review (Approved) needs to be given again. And there
needs to be a confirmation that a negative review (Changes requested)
has been addressed.
Closes: #505

from svc name in tool box, this is a workaround
to fix it.

Sometime rbd images are mapped even if the
connection timeout error occurs, this will
try to unmap if the received error message
is connection timeout.This will fix stale maps
and rbd image deletion issue

Image deletion takes time proportional to the size of the
image. Hence, ceph manager is enhanced to support async
deletion of an image, or rather passing the task of
deleting an image to the ceph manager.
This commit leverages the ceph manager enhancement in the CSI code.
NOTE: This is tested against a ceph cluster that is running
Ceph master version of the code. Once other releases
catch up in terms of the feature, the optimization would be
available to the CSI driver as well.

The container runtime CRI-O limits the number of PIDs to 1024 by
default. When many PVCs are requested at the same time, it is possible
for the provisioner to start too many threads (or go routines) and
executing 'rbd' commands can start to fail. In case a go routine can not
get started, the process panics.
The PID limit can be changed by passing an argument to kubelet, but this
will affect all pids running on a host. Changing the parameters to
kubelet is also not a very elegant solution.
Instead, the provisioner pod can change the configuration itself. The
pod is running in privileged mode and can write to /sys/fs/cgroup where
the limit is configured.
With this change, the limit is configured to 'max', just as if there is
no limit at all. The logs of the csi-rbdplugin in the provisioner pod
will reflect the change it makes when starting the service:
$ oc -n rook-ceph logs -c csi-rbdplugin csi-rbdplugin-provisioner-0
..
I0726 13:59:19.737678 1 cephcsi.go:127] Initial PID limit is set to 1024
I0726 13:59:19.737746 1 cephcsi.go:136] Reconfigured PID limit to -1 (max)
..
It is possible to pass a different limit on the commandline of the
cephcsi executable. The following flag has been added:
--pidlimit=<int> the PID limit to configure through cgroups
This accepts special values -1 (max) and 0 (default, do not
reconfigure). Other integers will be the limit that gets configured in
cgroups.

In unstage we now adhere to the transaction (or order of steps)
done in Stage. To enable this we stash the image meta data
into a local file on the staging path for use with unstage
request.
This helps in unmapping a stale map, in case the mount or
other steps in the transaction are complete.
