[BEAM-25] Temporarily reject stateful ParDo in SparkRunner (until support is added) 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 [Individual Contributor License Agreement](https://www.apache.org/licenses/icla.txt). --- R: @amitsela At present, the user-facing API for stateful `DoFn` is in the codebase but prevented from use. It is `ParDo.of(...)` that rejects stateful `DoFn`. In #1399 I am removing this rejection, so I need to add it to all runners until they support the API. I have also added a JUnit category so runners can exclude this from their `RunnableOnService` test suites.
