Return a representation of the resoure in the response to a PUT call

[gsilvis]

Currently, the user has to make a PUT and then a GET, to determine any aspect of the resource that the server fills in. If we make the PUT call return that information, then the second step can be skipped.

I am not sure whether this issue still exists or not. Close this for me. Please reopen it if necessary.

Don't wanna mark this closed; the issue suggests that we return something useful with PUT calls. It's still open for discussion.

For example, you run network_create which will assign your network a vlan id. But you don't know the id, so you have to follow up with a show_network call to determine what the vlan id was.
