[BEAM-2600] Add minimal python SDK harness container
----
> Python SDK harness container
> ----------------------------
>
> Key: BEAM-2600
> URL: https://issues.apache.org/jira/browse/BEAM-2600
> Project: Beam
> Issue Type: Sub-task
> Components: sdk-py-core
> Reporter: Kenneth Knowles
> Assignee: Henning Rohde
> Labels: portability
>
> In order to build a pipeline that invokes a Python UDF, we need to be able to
> construct something like this:
> {code}
> SdkFunctionSpec {
> environment = <python SDK harness>,
> spec = {
> urn = <python SDK pickled DoFn>,
> data = <pickled DoFn>
> }
> }
> {code}
> I could be out of date, but based on a couple of conversations I do not know
> that there exists anything we can put for "<python SDK harness>" today. For
> prototyping, it could be just a symbol that runners have to know. But
> eventually it should be something that runners can instantiate without
> knowing anything about the SDK that put it there. I imagine it may encompass
> "custom containers" eventually, though that doesn't block anything
> immediately.
> Update 9/11/2017: this issue will track the first portable SDK harness as per
> https://s.apache.org/beam-fn-api-container-contract, incl shared boot code
> and maven integration to build Go and Docker container images.
