Pytest stalling on the tier jobs [need investigation]

Issue Walk-through:

1. Pytest submits the Job to Saucelabs via it's tunnel.
2. Saucelabs executes the test, send back the results. At the same time, it should close the current opened session for test, but it doesn't.
3. This open session as a pytest worker associated with it gw0, gw1 etc., worker cannot stop as the session is still open.
4. The session on the saucelabs will stay open indefinitely, until a interrupt from within saucelab is triggered. This interrupt would kill -9 the open session without notifying the pytest worker.
5. In out automation, worker wait's indefinitely to receive data from sauce session.

Mostly occurs in long running tests, randomly in tier2 and tier3. Now that we know the issue, I will look into if we could add a timeout to workers executing tests and later identify all those test and re-check their logic

The issue, mentioned above creates a environment suitable for us hitting [1].

1. test item scheduling does not schedule N items to N workers pytest-dev/pytest-xdist#40
