feat: URL Forwarding

[dezren39]

It would be good to eventually enable a new resource for URL forwarding.

• Add URL Forward
• Get URL Forwarding

Unfortunately, the "Add URL Forward" request doesn't return the id of the forward result.

The id is available in the "Get URL Forwarding" command, so one could possibly use that before and after.

Eventually, I may try to contribute such a feature. Until then, creating this issue.
