DISCOVERY-86: fix test failing due to TIMEOUT

[mirekdlugosz]

camayoc/tests/qpc/cli/test_sources.py::test_clear_all fails when running the whole test suite.

The problem is in dependency between tests. When running a whole suite, there's a bunch of sources created by other tests. To ensure they do not interfere with this test, it first calls qpc source clear --all. However, clearing all sources can take some time, and pexpect can raise timeout exception before the command finishes.

On my machine:

$ RUN_SCANS=False pytest -v -s camayoc/tests/qpc/cli/test_sources.py -k test_add
========================================================== 2 failed, 67 passed, 68 deselected in 327.57s (0:05:27) ===========================================================
$ time qpc source clear --all
All sources were removed.

real    0m33.806s
user    0m4.242s
sys 0m0.160s

pexpect timeout is 30 seconds by default. And I think it has even more sources to clear during standard run.

With this PR, we raise pexpect timeout to give qpc time it needs. I guessed 2 minutes should be enough, but we may tweak that later. We can also disable timeouts completely, but that might result in blocking the suite completely, if there's a bug that prevents qpc from ever finishing.

Let's go with this maximum 2 minutes time-out for cleaning up.
