Description
UnboundedSource has pretty specific requirements of its runner (as well as its derived classes). We really need a systematic test of all of this. Inspiration is BEAM-306 which only showed up when I tried to run an actual pipeline.
Imported from Jira [BEAM-309](https://issues.apache.org/jira/browse/BEAM-309). Original Jira may contain additional context.

Contributor guide
Research direction
Start by reading the UnboundedSource runner contract described in the issue and reviewing BEAM-306 for the pipeline failure that motivated this request. Define a systematic test around those requirements, using the proposed UnboundedSourceFromHell, and consider the original BEAM-309 context; done means the runner's implied contract is covered by tests.
