This is currently slightly outdated but I can fix it up if the general direction is fine. Looking for initial feedback.

@eyakubovich Apologies on the delay. Overall approach LGTM. There has been a few changes in the data-structures recently and more coming via #429. But, we can get this merged if you can rebase to the latest and appropriate tests.

[eyakubovich]

I will give rebase shortly.

@eyakubovich Was wondering whether these new files should go inside a separate client package. At the end this is a libnetwork rest client implementation, I feel it should not reside along with the server api files.

[eyakubovich]

@aboch I can put it into a separate package. I was going off that the api package is all about remote API. Kind of like standard net/http package has both client and server code.

[aboch]

Thanks @eyakubovich, net/http is a good reference for this.

[eyakubovich]

There are some methods that return ErrNotImplemented or panic. If it makes sense, I can try to add the required functionality to the remote API and then implement them.

[aboch]

Thanks @eyakubovich, I think it makes sense to complete the client api.
I am not sure about ConfigureDriver(), for sure avoid to implement LeaveAll() as it is being removed (see #365).
