Rebase #465 on the latest libnetwork and move the function to sandbox

@aboch @mavenugo any feedback on this proposal?

[mavenugo]

though Interface is exposed as an osl interface, it feels odd to include it as part of the API.
osl is purely an internal implementation that provides os layer abstraction away from the clients.
Having this interface exposed via Interfaces() API which gives more control over life-cycle of the interface such as Remove makes me uncomfortable.

Lets hear from @mrjana on his opinion.

@boucher @mavenugo I actually created a issue regarding how to checkpoint/restore the container network correct. #524
There, I hope we can design the interface correctly and make some agreement. Thanks.
