Add Python implementation of GnuDIP client. Tests: - In testing container, configure Dynamic DNS with a (previously offlined) freedombox.rocks account. FreedomBox interface shows that the address has been updated. GnuDIP server also shows the correct IP address. - Running "gnudip update" and "dynamicdns update" actions produce the expected results.
