[NEMO-324] Distinguish Beam's run and waitUntilFinish methods (#187)

JIRA: [NEMO-324: Distinguish Beam's run and waitUntilFinish methods](https://issues.apache.org/jira/projects/NEMO/issues/NEMO-324)

**Major changes:**
- Gets rid of the UnsupportedOperation, makes `waitUntilFinish` method to a meaningful one.
- Runs the application asynchronously on the `run` method.

**Minor changes to note:**
- Add the examples output directory to the gitignore.

**Tests for the changes:**
- I've added a same word count program that has a timeout of 1 second, and a test to confirm that it aborts after 1 second.
- Existing tests cover other changes.

**Other comments:**
- None

Closes #187
