This commit adds `pytest-rerunfailures` in requirements.txt so we can
retry failing test in testinfra to avoid false positive. (eg: sometimes it
can happen for some reason a service takes too much time to start)

In order to support ansible 2.8 with testinfra we need to use the
latest release (3.0.x).
Adding ssh-config option to py.test.
Also bumping the pytest and xdist version.
