This commit removes the `Update` functionality from the admin API. While this is technically a breaking change I think this will not cause any harm because: - The KMS admin API is not complete, yet. At the moment only the status can be fetched. - The `mc` integration hasn't been merged yet. So no `mc` client could have used this API in the past. The `Update`/`Rewrap` status is not useful anymore. It provided a way to migrate from one master key version to another. However, KES does not support the concept of key versions. Instead, key migration should be implemented as migration from one master key to another. Basically, the `Update` functionality has been implemented just for Vault.
