Updated Streaming tests

Major changes are as follows:
- Added more tests - updateStateByKey, GroupByKeyAndWindow, ReduceByKeyAndWindow
- Updated config and main run script to make it easier to disable tests of certain modules, without having comments the tests of those modules one-by-one (maybe I should consider uncommenting all the tests, and use the variables to disable them by default)

It looks like this is only a marginal compactness win:

```
streaming_window_duration_opts(duration)
[OptionSet("window-duration", [duration])]
```
