[BEAM-551] Add ValueProvider class (Take 2)
My branch had become a dumpster fire, so I'm opening a fresh PR (history is
here: https://github.com/apache/incubator-beam/pull/827).
Add a basic implementation of StaticValueProvider and DynamicValueProvider.
@dhalperi , could you please take a look? Hoping the jackson API surface
test failures are easy to fix.

> Support Dynamic PipelineOptions
> -------------------------------
>
> Key: BEAM-551
> URL: https://issues.apache.org/jira/browse/BEAM-551
> Project: Beam
> Issue Type: New Feature
> Components: beam-model
> Reporter: Sam McVeety
> Assignee: Frances Perry
> Priority: Minor
>
> During the graph construction phase, the given SDK generates an initial
> execution graph for the program. At execution time, this graph is
> executed, either locally or by a service. Currently, Beam only supports
> parameterization at graph construction time. Both Flink and Spark supply
> functionality that allows a pre-compiled job to be run without SDK
> interaction with updated runtime parameters.
> In its current incarnation, Dataflow can read values of PipelineOptions at
> job submission time, but this requires the presence of an SDK to properly
> encode these values into the job. We would like to build a common layer
> into the Beam model so that these dynamic options can be properly provided
> to jobs.
> Please see
> https://docs.google.com/document/d/1I-iIgWDYasb7ZmXbGBHdok_IK1r1YAJ90JG5Fz0_28o/edit
> for the high-level model, and
> https://docs.google.com/document/d/17I7HeNQmiIfOJi0aI70tgGMMkOSgGi8ZUH-MOnFatZ8/edit
> for
> the specific API proposal.
