Handle IPv6 URLs in devolo Home Network

[Shutgun]

Proposed change

Sometimes the device detection discovers devolo Home Network devices via IPv6. In that case, the DeviceInfo.configuration_url causes a ValueError because the octets are treated as port. So we need to add brackets in case of IPv6.

My current setup does not have properly configured IPv6, so I'm not able to test this in a real setup ...
