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().

This new KMS uses a Kubernetes ServiceAccount from a Tenant (Namespace)
to connect to Hashicorp Vault. The provisioner and node-plugin will
check for the configured ServiceAccount and use the token that is
located in one of the linked Secrets. Subsequently the Vault connection
is configured to use the Kubernetes token from the Tenant.
