    Start transition to boto3 in s3api tests.

    Adds the scaffolding required for tests to use boto3 and converts the
    test_bucket.py tests to the new interface. Follow on patches will
    convert the other tests to use the boto3 library.

    Notable changes: we no longer try to reach for the equivalent of
    `boto.make_request()` and instead rely on the boto3/botocore event
    system to mutate requests as necessary (or to disable pre-flight
    validators).
