The Key Management Interoperability Protocol (KMIP)
is an extensible communication protocol
that defines message formats for the manipulation
of cryptographic keys on a key management server.
Ceph-CSI can now be configured to connect to
various KMS using KMIP for encrypting RBD volumes.

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.

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 kmsConfig type in the e2e suite has been enhanced with two functions
that make it possible to validate the destruction of deleted keys.

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.

The ServiceAccount "ceph-csi-vault-sa" is expected to be placed in the
Namespace "tenant" so that the provisioner and node-plugin fetch the
ServiceAccount from a Namespace where Ceph-CSI is not deployed.

* 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)
