When running the kubernetes cluster with one single privileged
PodSecurityPolicy which is allowing everything the nodeplugin
daemonset can fail to start. To be precise the problem is the
defaultAllowPrivilegeEscalation: false configuration in the PSP.
Containers of the nodeplugin daemonset won't start when they
have privileged: true but no allowPrivilegeEscalation in their
container securityContext.
Kubernetes will not schedule if this mismatch exists cannot set
allowPrivilegeEscalation to false and privileged to true:

This argument in csi-snapshotter sidecar allows us to receive
snapshot-name/snapshot-namespace/snapshotcontent-name metadata in the
CreateSnapshot() request.
For ex:
csi.storage.k8s.io/volumesnapshot/name
csi.storage.k8s.io/volumesnapshot/namespace
csi.storage.k8s.io/volumesnapshotcontent/name
This is a useful information which can be used depend on the use case we
have at our driver. The features like adding metadata to snapshot image
can consume this based on the need.

The API is extended for generation of the NFS CSIDriver object. The
YAML file under deploy/ was created by `yamlgen`.
The contents of the csidriver.yaml file is heavily based on the upstream
CSIDriver from the Kubernetes csi-driver-nfs project.
Because ./tools/yamlgen uses the API, it gets copied under vendor/ .
This causes two copies of the API to be included in the repository, but
that can not be prevented, it seems.

With Amazon STS and kubernetes cluster is configured with
OIDC identity provider, credentials to access Amazon KMS
can be fetched using oidc-token(serviceaccount token).
Each tenant/namespace needs to create a secret with aws region,

Ceph-CSI will assume the given role with oidc token and access

Mounts managed by ceph-fuse may get corrupted by e.g. the ceph-fuse process
exiting abruptly, or its parent container being terminated, taking down its
child processes with it.
This commit adds checks to NodeStageVolume and NodePublishVolume procedures
to detect whether a mountpoint in staging_target_path and/or target_path is
corrupted, and remount is performed if corruption is detected.

The CentOS 8 repository for Apache Arrow has been removed. This causes
container-image builds fail with the following error:
Errors during downloading metadata for repository 'apache-arrow-centos':
- Status code: 404 for https://apache.jfrog.io/artifactory/arrow/centos/8/x86_64/repodata/repomd.xml (IP: 54.190.66.70)
Error: Failed to download metadata for repo 'apache-arrow-centos': Cannot download repomd.xml: Cannot download repodata/repomd.xml: All mirrors were tried
The Ceph base image has `arrow/centos/8` configured, maybe Apache Arrow
offers a CentOS Stream 8 repository now? Once the Ceph container-image
has been updated, the repository can be enabled again.
Ceph-CSI does not depend on Apache Arrow, so there is no functional
change by disabling the repository.

Problem:
--------
1. rbd-nbd by default logs to /var/log/ceph/ceph-client.admin.log,
Unfortunately, container doesn't have /var/log/ceph directory hence
rbd-nbd is not logging now.
2. Rbd-nbd logs are not persistent across nodeplugin restarts.
Solution:
--------
Provide a host path so that log directory is made available, and the
logs persist on the hostnode across container restarts.

Problem:
-------
For rbd nbd userspace mounter backends, after a restart of the nodeplugin
all the mounts will start seeing IO errors. This is because, for rbd-nbd
backends there will be a userspace mount daemon running per volume, post
restart of the nodeplugin pod, there is no way to restore the daemons
back to life.
Solution:
--------
The volume healer is a one-time activity that is triggered at the startup
time of the rbd nodeplugin. It navigates through the list of volume
attachments on the node and acts accordingly.
For now, it is limited to nbd type storage only, but it is flexible and
can be extended in the future for other backend types as needed.
From a few feets above:
This solves a severe problem for nbd backed csi volumes. The healer while
going through the list of volume attachments on the node, if finds the
volume is in attached state and is of type nbd, then it will attempt to
fix the rbd-nbd volumes by sending a NodeStageVolume request with the
required volume attributes like secrets, device name, image attributes,
and etc.. which will finally help start the required rbd-nbd daemons in
the nodeplugin csi-rbdplugin container. This will allow reattaching the
backend images with the right nbd device, thus allowing the applications
to perform IO without any interruptions even after a nodeplugin restart.

Nodeplugin needs below cluster roles:
persistentvolumes: get
volumeattachments: list, get
These additional permissions are needed by the volume healer. Volume healer
aims at fixing the volume health issues at the very startup time of the
nodeplugin. As part of its operations, volume healer has to run through
the list of volume attachments and understand details about each
persistentvolume.
The later commits will use these additional cluster roles.
