This commit adds a new admin API for creating master keys. An admin client can send a POST request to: ``` /minio/admin/v3/kms/key/create?key-id=<keyID> ``` The name / ID of the new key is specified as request query parameter `key-id=<ID>`. Creating new master keys requires KES - it does not work with the native Vault KMS (deprecated) nor with a static master key (deprecated). Further, this commit removes the `UpdateKey` method from the `KMS` interface. This method is not needed and not used anymore.
