    [BEAM-437] Support data-dependent writes using BigQuery batch load jobs

    This pull request adds support for data-dependent writes when using batch load jobs. This
is accomplished via refactoring BigQueryIO into separate transforms, with the first being
a common PrepareWrite transform that determines which tables records should go to, followed
by transforms that know how to interpret this.
    One side benefit of this refactoring is that the different components can be used on their
own. For example, one request has been to allow dynamic creation of datasets in BigQueryIO.
A user can now accomplish this by running PrepareWrite themselves, followed by their own custom
transform to create datasets, and then the remaining transform.
    In order to test this, BigQueryIOTest was modified to use a proper fake service, removing
the dependency on mockito.
