    Bump os-log-merger version in post_test_hook

    The 1.0.6 version of os-log-merger exploded in cases where
    log files contained \0 characters. 1.1.0 fixes such issue.

    Don't return null-byte separated string from ExternalProcess.cmdline()

    Instead construct the string using psutil.Process.cmdline() method that
    will parse the data from kernel for us and will return a proper
    space-separated command line (plus will provide some more safety
    guarantees, e.g. against zombies).

    This change also introduces a new psutil dependency for neutron. Before
    that, the library was used in functional tests only, and with a minimal
    version number that is not compatible with global-requirements.txt or
    .cmdline(). Moved the requirement into runtime requirements.

This issue was fixed in the openstack/neutron 11.0.0.0b1 development milestone.
