Implement "network rbac set" command

Add "network rbac set" command which just supports
setting a target project.
Also, This patch adds the doc, unit test and functional test.
But there is a bug of showing network RBAC
https://bugs.launchpad.net/python-openstacksdk/+bug/1608903
We need to skip the functional test before this bug fixed.
