Add BeamFnDataReceiver and make process, finish and start run on the same
thread to support metrics.

@robertwb This to address a gap in the current Java SDK. The thread that
executes StartBundle/FinishBundle calls is different from the thread that the
calls ProcessElement breaking the thread safety expectations of DoFn authors.
This does make it easier to implement the metrics API as it exists today but
that is a side effect.
