0c33a33d5c rbd: add kmip encryption type
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.

4f0bb2315b rbd: add aws-sts-metdata encryption type
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.

Refer: https://docs.aws.amazon.com/STS/latest/APIReference/welcome.html

9200bc7a00 rbd: Implement Key Protect KMS integration for Ceph CSI
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.

bb60173a98 e2e: add verifyKeyDestroyed() for validating vaultDestroyKeys
The kmsConfig type in the e2e suite has been enhanced with two functions
that make it possible to validate the destruction of deleted keys.

f584db41e6 util: add vaultDestroyKeys option to destroy Vault kv-v2 secrets
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.

f2d5c2e0df util: add vaultAuthNamespace option for Vault KMS
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.

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.

b700fa43e6 doc: add example for Tenant ServiceAccount
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.

669dc4536f Reduce encryption KMS configuration SC parameters
* 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

419ad0dd8e Adds per volume encryption with Vault integration
- 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)
