d941e5abac util: make parseTenantConfig() usable for modular KMSs
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().

3d7d48a4aa util: VaultTenantSA KMS implementation
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.

3352d4aabd rbd: add user secret based metadata encryption
This commit adds capability to `metadata` encryption
to be able to fetch `encryptionPassphrase` from user
specified secret name and namespace(if not specified,
will default to namespace where PVC was created).

This behavior is followed if `secretName` key is found
in the encryption configuration else defaults to fetching
`encryptionPassphrase` from storageclass secrets.

0837c05be0 rbd: set scheduling interval on snapshot mirrored image
Mirror-snapshots can also be automatically created on a
periodic basis if mirror-snapshot schedules are defined.
The mirror-snapshot can be scheduled globally, per-pool,
or per-image levels. Multiple mirror-snapshot schedules
can be defined at any level.

To create a mirror-snapshot schedule with rbd, specify
the mirror snapshot schedule add command along with an
optional pool or image name; interval; and optional start time:

The interval can be specified in days, hours, or minutes
using d, h, m suffix respectively. The optional start-time
can be specified using the ISO 8601 time format. For example:

```
$ rbd --cluster site-a mirror snapshot schedule
  add --pool image-pool --image image1 24h 14:00:00-05:00
