The current top-level Node API exposes the set of things necessary to use the library, but not necessarily in the most reasonable way. Plus, load produces a possibly unintuitive combination of Protobuf.js output and grpc output.

It looks like there are two primary changes that need to be made for this:

• Remove the two-step server construction process (Change Node server construction interface #2456)
• Remove the server-wide metadata handler (Remove Node server-wide metadata handler #2465)
