Please add support for certificate-authority-data in set_cluster().

[mattmeye]

Hello, can you add support "certificate" in the set_cluster method, please?

Sometimes you may want to use Base64-encoded data embedded here instead of separate certificate files; in that case you need to add the suffix -data to the keys, for example, certificate-authority-data, client-certificate-data, client-key-data. source

Kind regards,
matt
