    tests: don't rely on configuration files outside tests directory

    etc/... may be non existent in some build environments. It's also pip
    does not install those files under site-packages neutron module, so
    paths relative to python files don't work.

    So instead of using relative paths to etc/... contents, maintain our own
    version of configuration files. It means we need to maintain tests only
    policy.json file too, in addition to neutron.conf.test and
    api-paste.ini.test.

    Ideally, we would make etc/policy.json copied under site-packages in
    addition to /etc/neutron/. In that way, we would not maintain a copy of
    policy.json file in two places.

    Though it seems that setuputils does not have a good way to install
    files under site-packages that would consider all the differences
    between python environments (specifically, different prefixes used in
    different systems).

    Note: it's not *absolutely* needed to update the test policy.json file
    on each next policy update, though it will be needed in cases when we
    want to test policy changes in unit tests. So adding a check to make
    sure files are identical.

    This partially reverts commit 1404f33b50452d4c0e0ef8c748011ce80303c2fd.
