@Rubiojr and I enabled to operate routers with openstack.

https://github.com/fog/fog/pull/1586

We collaborate to build a patch which enable to operate routers with openstack.

This code was tested by @Rubiojr and I with OpenStack Folsom and Grizzly release versions. and I tested by mock, too. 

Perhaps, some fails will occure with tests/openstack/requests/network/router_tests.rb. If that is not good, please remove this file. all of other mock tests are ok.

Regards.
