Kazoo 3003: Allow superduper admins to edit port requests in protected states

Superduper admins are unable to edit a port request in any state only the have access to (e.g.submitted/scheduled). See issue [KAZOO-3003](https://2600hz.atlassian.net/browse/KAZOO-3003).

In addition, according to wh_port_request it is possible to resubmit a rejected port. It makes sense then that a user should be able to edit their port request before resubmitting it.
Thanks for updating here. Want to be the bestest and convert https://github.com/2600hz/kazoo/blob/master/applications/crossbar/doc/port_request.curl.txt to a proper Markdown file similar to the other API docs? It needs the updated port states as well. :)
