Barnabás Pőcze 74c0e8cbf1 apps: lc-compliance: Merge CaptureBalanced and CaptureUnbalanced
The above two classes have very similar implementations, in fact, the
only essential difference is how many requests are queued. `CaptureBalanced`
queues a predetermined number of requests, while `CaptureUnbalanced`
queues requests without limit.

This can be addressed by introducing a "capture" and a "queue" limit
into the `Capture` class, which determine at most how many requests
can be queued, and how many request completions are expected before
stopping.
