is_older_than and is_newer_than don't support timezone aware datetimes

[Michael H Wilson]

Pass a datetime that is offset aware into openstack.common.timeutils.is_newer_than or is_older_than and you will get this:

TypeError: can't subtract offset-naive and offset-aware datetimes

See https://review.openstack.org/#/c/60992/ Patch set #1 for another example.

    Avoid TypeError in is_older_than, is_newer_than

    datetime doesn't like to subtract offset-naive and
    offset-aware datetimes. To fix this we convert all
    datetimes that are passed in to offset-naive objects.
