82557e3f34 util: allow configuring VAULT_BACKEND for Vault connection
It seems that the version of the key/value engine can not always be
detected for Hashicorp Vault. In certain cases, it is required to
configure the `VAULT_BACKEND` (or `vaultBackend`) option so that a
successful connection to the service can be made.

The `kv-v2` is the current default for development deployments of
Hashicorp Vault (what we use for automated testing). Production
deployments default to version 1 for now.

d941e5abac util: make parseTenantConfig() usable for modular KMSs
parseTenantConfig() only allowed configuring a defined set of options,
and KMSs were not able to re-use the implementation. Now, the function
parses the ConfigMap from the Tenants Namespace and returns a map with
options that the KMS supports.

The map that parseTenantConfig() returns can be inspected by the KMS,
and applied to the vaultTenantConnection type by calling parseConfig().

fd9fee74de e2e: disable iss validation in Hashicorp Vault
Testing encrypted PVCs does not work anymore since Kubernetes v1.21. It

2945f7b669 cleanup: stick to standards when using dollar-sign in md
MD014 - Dollar signs used before commands without showing output
The dollar signs are unnecessary, it is easier to copy and paste and
less noisy if the dollar signs are omitted. Especially when the
command doesn't list the output, but if the command follows output
we can use `$ ` (dollar+space) mainly to differentiate between
command and its ouput.

scenario 1: when command doesn't follow output
```console
cd ~/work
```

scenario 2: when command follow output (use dollar+space)
```console
$ ls ~/work

Obviously expecting a pool with name `rbd` or CephFS name `myfs`
will be a limitation, as the pool/fs is created by admin manually,
let them choose the name that suits their requirement and come back
edit it in the storage class.

Making the pool/fs name as required field will give more attention,
else with new users it will be mostly left unedited until one hit
the errors saying no pool/fs exists.

This patch clips-off the default pool/fs name and make it a mandatory
field.

temp clone image in the chain if available
* Reserve the key and values in omap (this will help us to
avoid the leak as it's not reserved earlier as we have returned
ABORT (the request may not come back))
* Create a snapshot of rbd image
* Clone the snapshot (temp clone)
* Delete the snapshot
* Snapshot the temp clone
* Clone the snapshot (final clone)
* Delete the snapshot

```bash
1) check the image depth of the parent image if flatten required
add a task to flatten image and return ABORT to avoid leak
(hardlimit-2 and softlimit-2 check will be done)
2) Reserve omap keys
2) rbd snap create <RBD image for src k8s volume>@<random snap name>
3) rbd clone --rbd-default-clone-format 2 --image-feature
layering,deep-flatten <RBD image for src k8s volume>@<random snap>

4) rbd snap rm <RBD image for src k8s volume>@<random snap name>

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.

02bcb5f16a Enable leader election in v1.14+
Use Deployment with leader election instead of StatefulSet

Deployment behaves better when a node gets disconnected
from the rest of the cluster - new provisioner leader
is elected in ~15 seconds, while it may take up to
5 minutes for StatefulSet to start a new replica.

c5762b6b5c Modify RBD plugin to use a single ID and move the id and key into the secret
RBD plugin needs only a single ID to manage images and operations against a
pool, mentioned in the storage class. The current scheme of 2 IDs is hence not
needed and removed in this commit.

Further, unlike CephFS plugin, the RBD plugin splits the user id and the key
into the storage class and the secret respectively. Also the parameter name
for the key in the secret is noted in the storageclass making it a variant and
hampers usability/comprehension. This is also fixed by moving the id and the key
to the secret and not retaining the same in the storage class, like CephFS.

9a03d735a2 Remove redundant pool parameter from snapshot class
The SnapshotClass for RBD requires a pool parameter. This is redundant
as a snapshot is not created on a different pool than the source image
of the snapshot (refer rbd man page).

Further, when a snapshot needs to be created its source CSI VolumeID
is passed to the creation call, and hence the source volumes pool
needs to be reused to create the snapshot.

Similarly to clone a snapshot, the create request would come in with a
SnapshotID to help identify the snapshot pool, and the same create
request parameters would contain the storage class based pool parameter
to create the clone into (as clones can be in different pools as
compared to their parent snapshots).

Thus, the parameter pool seems redundant in the snapshot class and
should be removed to improve ease of use.

b9cd0e18ad Make CephFS plugin stateless reusing RADOS based journal scheme
This is a part of the stateless set of commits for CephCSI.

This commit removes the dependency on config maps to store cephFS provisioned
volumes, and instead relies on RADOS based objects and keys, and required
CSI VolumeID encoding to detect the provisioned volumes.

Changes:
- Provide backward compatibility to provisioned volumes by older plugin versions (1.0.0 or older)
- Remove Create/Delete support for statically provisioned volumes (fixes )
- Added namespace support to RADOS OMaps and used the same to store RADOS CSI objects and keys in the CephFS metadata pool
- Added support to mention fsname for CephFS provisioning (fixes )
- Changed field name in CSI Identifier to 'location', to denote a pool or fscid
- Updated mounter cache to use new scheme
- Required Helm manifests are updated
- Required documentation and other manifests are updated
- Made driver option 'metadatastorage' as optional, as fresh installs do not need to specify the same

Testing done:
- Create/Mount/Delete PVC
- Create/Delete 5 PVCs
- Mount version 1.0.0 PVC
- Delete version 1.0.0 PV
- Mount Statically defined PV/PVC/Pod
- Mount Statically defined version 1.0.0 PV/PVC/Pod
- Delete Statically defined version 1.0.0 PV/PVC/Pod
- Node restart when mounted to test mountcache
- Use InstanceID other than 'default'
- RBD basic round of tests, as namespace is added to OMaps
- csitest against ceph-fs plugin
  - NOTE: CephFS plugin still does not detect and address already created
  volumes but of a different size
- Test not providing any value to the metadata storage parameter

- Updated documentation
- Updated manifests
- Updated Helm chart

Based on the review comments addressed the following,
- Moved away from having to update the pod with volumes
when a new Ceph cluster is added for provisioning via the
CSI driver

- The above now used k8s APIs to fetch secrets
  - TBD: Need to add a watch mechanisim such that these
secrets can be cached and updated when changed

- Folded the Cephc configuration and ID/key config map
and secrets into a single secret

- Provided the ability to read the same config via mapped
or created files within the pod

Tests:
- Ran PV creation/deletion/attach/use using new scheme
StorageClass
- Ran PV creation/deletion/attach/use using older scheme
to ensure nothing is broken
- Did not execute snapshot related tests

- PV provisioning and staging using cluster-id in storage class
- PV provisioning and staging using MON list in storage class

Did not test,

6ec1196f47 Rework multi-node-multi-writer feature
This commit reverts the initial implementation of the
multi-node-multi-writer feature:
  commit: b5b8e46460

It replaces that implementation with a more restrictive version that
only allows multi-node-multi-writer for volumes of type `block`

With this change there are no volume parameters required in the stoarge
class, we also fail any attempt to create a file based device with
multi-node-multi-write being specified, this way a user doesn't have to
wait until they try and do the publish before realizing it doesn't work.

This change adds the ability to define a `multiNodeWritable` option in
the Storage Class.

This change does a number of things:
1. Allow multi-node-multi-writer access modes if the SC options is
enabled
2. Bypass the watcher checks for MultiNodeMultiWriter Volumes
3. Maintains existing watcher checks for SingleNodeWriter access modes
regardless of the StorageClass option.
