    [BEAM-115] Add proto definition for Runner API

    Be sure to do all of the following to help us incorporate your contribution
    quickly and easily:
     - [x] Make sure the PR title is formatted like:
       `[BEAM-<Jira issue #>] Description of pull request`
     - [x] Make sure tests pass via `mvn clean verify`. (Even better, enable
           Travis-CI on your fork and ensure the whole test matrix passes).
     - [x] Replace `<Jira issue #>` in the title with the actual Jira issue
           number, if there is one.
     - [x] If this contribution is large, please file an Apache

    These are the protocol buffers definitions corresponding to the Avro schema proposed in
    Differences from the schema there:
     - Graph structure is decoupled from what data annotations the nodes
     - Adopted names from the Fn API's proto for things that overlap
     - Added explicit URNs and payloads for primitives
     - Added outline of state and timers
     - Added Environment URLs
    I would like to merge this and separately port the Fn API to use shared structures as
appropriate, since that may involve more extensive coding work.
    Unlike #662, this is _not_ a WIP just for discussion. This is intended for immediate use
as the serialization format for various pieces of the pipeline to unblock work on the Fn API.
