One of the main uses of context.Context is to provide cancellation for go-routines, including API requests. While all user-facing bindings already used a context parameter, it was only used to pass the client information around. This commit changes the internal DoRequest wrapper to take an additional context argument, and pass that to the http request. Previously, the context was derived from context.Background(), which made it impossible to cancel once started. All the convenience wrappers already supported the context parameter, so the only user facing change is that cancelling those context now works as one would expect.
