RuntimeWarning generated by is_compatible()

[John L. Villalovos]

In Ironic during a run of: $ tox -e py35

We see 11,000+ RuntimeWarnings like this:

  RuntimeWarning: You have iterated over the result of pkg_resources.parse_version. This is a legacy behavior which is inconsistent with the new version class introduced in setuptools 8.0. In most cases, conversion to a tuple is unnecessary. For comparison of versions, sort the Version instances directly. If you have another use case requiring the tuple, please file a bug with the setuptools project describing that need.'

This is caused by this line:
https://github.com/openstack/oslo.utils/blob/dd1ceea294b36dc7f3e4546498b092c3fd13875f/oslo_utils/versionutils.py#L45

When it tries to index the value it causes the __iter__ operator to run and then the above RuntimeWarning is generated.

    Prevent deprecation error messages from pkg_resources

    Currently pkg_resources is creating this warning message:

        RuntimeWarning: You have iterated over the result of
        pkg_resources.parse_version. This is a legacy behavior which is
        inconsistent with the new version class introduced in setuptools
        8.0. In most cases, conversion to a tuple is unnecessary. For
        comparison of versions, sort the Version instances directly. If
        you have another use case requiring the tuple, please file a bug
        with the setuptools project describing that need.

    Get the major_version directly from the version string passed in
    instead so that the warning message is not raised.
