Hello Team,

In OpenShift 3.11 we had an option to manually rotate key for etcd encryption when enabled for it by having a `EncryptionConfig` file which used to get mentioned in the `master-config.yaml` file.

In OpenShift 4.x we do not have any resource with name `EncryptionConfig` and hence enable to manually rotate the keys.

Can we have the ability to manually rotate the keys for etcd when the encryption is enabled.
Ability to use a KMS server to rotate the keys and to alter the encryption configuration like we had in 3.11.
