    Set wsgi.keep_alive=False globally for tests

    This was previously set for all functional API samples
    tests to try and fix a weird issue where requests and responses
    seemed to get mixed up between the compute API wsgi service
    fixture used in the API samples functional tests and the
    Placement API functional tests.

    However, we're also seeing these weird mixup issues in
    non-API samples tests, and there are other wsgi server fixtures
    that should be setting this, like the OSMetadataServer
    fixture. And there are functional tests that don't inherit from
    _IntegratedTestBase so we should just set this globally to be
    safe.
