[BEAM-34][BEAM-145] Make WindowingStrategy combine WindowFn with OutputTimeFn 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). --- Previously: - Any user-specified OutputTimeFn overrode the WindowFn#getOutputTime - WindowFn#getOutputTimeFn provided a default OutputTimeFn - The default varied from "earliest" to "end of window" Now: - The user-specified OutputTimeFn is used to combine the WindowFn's assigned output timestamps. - The WindowFn does not provide the default. - The default is always to output at end of window. For each of the tests that this effects, I had a choice: either update the timestamps in the test to be the end of window, or explicitly reset the windowing strategy to choose the minimum timestamp. The latter generally gets more useful coverage, since the latter is fairly trivial, so I generally favored it. It is also easier to migrate to. And most of the tests are overspecified anyhow and should not be examining the timestamps.
