Add more integration tests for BigQueryIO

Seems like we currently only have a single test that directly read using a query.

[https://github.com/apache/beam/blob/328129bf033bc6be16bc8e09af905f37b7516412/examples/java/src/test/java/org/apache/beam/examples/cookbook/BigQueryTornadoesIT.java](https://github.com/apache/beam/blob/328129bf033bc6be16bc8e09af905f37b7516412/examples/java/src/test/java/org/apache/beam/examples/cookbook/BigQueryTornadoesIT.java)

We should consider adding more integration tests. For example,

(1) Read directly from a given table and a dataset.

(2) Read from a federated table.

(3) Read using BQ legacy SQL.

(4) Read from a table with nested/repeated fields.

(5) Read from non-standard BQ regions (for example, Japan).

Also, we should consider adding tests for BQ streaming writes once we have framework support for that.
