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.

A tenant can place a ConfigMap in their Kubernetes Namespace with
configuration options that differ from the global (by the Storage Admin
set) values.
The ConfigMap needs to be located in the Tenants namespace, as described
in the documentation

Deploying Vault still fails on occasion. It seems that the
imagePullPolicy has not been configured for the container yet.

On occasion deploying Vault fails. It seems the vault-init-job batch job
does not use a full-qualified-image-name for the "vault" container.

Add "sys/mounts" so that VaultBackendKey does not need to be set. The
libopenstorage API detects the version for the key-value store in Vault
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.

Images that have an unqualified name (no explicit registry) come from
Docker Hub. This can be made explicit by adding docker.io as prefix. In
addition, the default :latest tag has been added too.

we need to provide access to the Service
account created with helm charts to access
the vault service.

* 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)
