### Set legal hold on an object

PutObject API allows setting legal hold using `x-amz-object-lock-legal-hold` header.

```sh

                    c.setting("xpack.security.http.ssl.keystore.path", "test-node.jks");
                    c.keystore("xpack.security.transport.ssl.keystore.secure_password", "keypass");
                    c.keystore("xpack.security.http.ssl.keystore.secure_password", "keypass");
                    // copy keystores & certs into config/
                    c.extraConfigFile(nodeKeystore.getName(), nodeKeystore);
