Permission denied error in unit tests

[Salvatore Orlando]

Unit tests are intermittently failing because of permission denied errors on /var/lib/neutron

It seems tmpdir fixtures are not being used.

    Use a temp dir for CONF.state_path

    external_pids will defaults to $state_path(/var/lib/neutron)/external/pids
    which isn't accessible when running unit tests so use a tempdir for
    CONF.state_path. This bug arose when oslo.config 1.3.0 came out which
    fixed bug #1282250 (I4324bda6f3de3cdf05f8eb3cf16052c04018dec8) and
    caused this issue.
