Sending binaries over relations

[Merlijn Sebrechts]

@José: I worry that this will become a big strain to the state server. I
don't know much about the internal architecture to be certain of this,
though..

@Matthew: This would side-step jujuresources. It might be feasible if
jujuresources could provide a way for the Charm to Share that resource,
though... Even then, we might get into trouble if the binaries aren't
included as a resource but are compiled during installation...
