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,
role and CMK ARN.
Ceph-CSI will assume the given role with oidc token and access
aws KMS, with given CMK to encrypt/decrypt DEK which will stored
in the image metdata.

considering IBM has different crypto services (ex: SKLM) in place, its
good to keep the configmap key names with below format
`IBM_KP_...` instead of `KP_..`
so that in future, if we add more crypto services from IBM we can keep
similar schema specific to that specific service from IBM.
Ex: `IBM_SKLM_...`

This commit adds the support for HPCS/Key Protect IBM KMS service
to Ceph CSI service. EncryptDEK() and DecryptDEK() of RBD volumes are
done with the help of key protect KMS server by wrapping and unwrapping
the DEK and by using the DEKStoreMetadata.

The command `vault monitor` can be used to stream logging from the Vault
service. This is very helpful while debugging Vault configuration
failures.
By adding a 2nd container to the Vault deployment, it is now possible to
get the messages from the Vault service by running
$ kubectl logs -c monitor <vault-pod-0123abcd>
This will be very useful when the e2e tests do not delete the deployment
after a failure and fetch the logs from all containers.

Hashicorp Vault does not completely remove the secrets in a kv-v2
backend when the keys are deleted. The metadata of the keys will be
kept, and it is possible to recover the contents of the keys afterwards.
With the new `vaultDestroyKeys` configuration parameter, this behaviour
can now be selected. By default the parameter will be set to `true`,
indicating that the keys and contents should completely be destroyed.
Setting it to any other value will make it possible to recover the
deleted keys.

The new `vaultAuthNamespace` configuration parameter can be set to the
Vault Namespace where the authentication is setup in the service. Some
Hashicorp Vault deployments use sub-namespaces for their users/tenants,
with a 'root' namespace where the authentication is configured. This
requires passing of different Vault namespaces for different operations.
Example:
- the Kubernetes Auth mechanism is configured for in the Vault
Namespace called 'devops'
- a user/tenant has a sub-namespace called 'devops/website' where the
encryption passphrases can be placed in the key-value store
The configuration for this, then looks like:
vaultAuthNamespace: devops
vaultNamespace: devops/homepage
Note that Vault Namespaces are a feature of the Hashicorp Vault
Enterprise product, and not part of the Open Source version. This
prevents adding e2e tests that validate the Vault Namespace
configuration.

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.

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().

Testing encrypted PVCs does not work anymore since Kubernetes v1.21. It
seems that disabling the iss validation in Hashicorp Vault is a
relatively simple workaround that we can use instead of the more complex
securing of the environment like should be done in production
deployments.

The ConfigMap needs to be located in the Tenants namespace, as described

Add "sys/mounts" so that VaultBackendKey does not need to be set. The

by reading "sys/mounts". Without permissions to read this endpoint, the
VaultBackendKey is required to be configured.

Docker Hub offers a way to pull official images without any project
prefix, like "docker.io/vault:latest". This does a redirect to the
images located under "docker.io/library".
By using the full qualified image name, a redirect gets removed while
pulling the images. This reduces the likelyhood of hittin Docker Hub
pull rate-limits.

* moves KMS type from StorageClass into KMS configuration itself
* updates omapval used to identify KMS to only it's ID without the type
why?
1. when using multiple KMS configurations (not currently supported)
automated parsing of kms configuration will be failing because some
entries in configs won't comply with the requested type
2. less options are needed in the StorageClass and less data used to
identify the KMS

- adds proposal document for PVC encryption from PR448
- adds per-volume encription by generating encryption passphrase
for each volume and storing it in a KMS
- adds HashiCorp Vault integration as a KMS for encryption passphrases
- avoids encrypting volume second time if it was already encrypted but
no file system created
- avoids unnecessary checks if volume is a mapped device when encryption
was not requested
- prevents resizing encrypted volumes (it is not currently supported)
- prevents creating snapshots from encrypted volumes to prevent attack
on encryption key (security guard until re-encryption of volumes
implemented)
