    monkey patch stdlib before importing other modules

    Some oslo libraries assume that stdlib is already patched when
    they are imported (e.g. oslo_concurrency.processutils tests the
    'time' module for monkey_patching to detect which 'subprocess'
    module to import.

    This can cause issues when things like test frameworks import
    modules that monkey_patch, as the order imports are made can break
    this kind of check. It is always good to monkey patch as soon as
    possible, hence trying to do the patching in neutron/__init__.py.

    This is an alternative to https://review.openstack.org/#/c/153225/
    which just patches neutron/tests/__init__.py. Unfortunately, just
    monkey_patching in tests/__init__.py didn't fix all of the issues
    I ran into. For example, tempest tests were failing with timeouts.
