Review comment:
Since `ReadFromBigQuery` is the user-facing transform, it should have all
the Pydoc.
That being said, I'll defer @chamikaramj whether we want to expose this
already.

> Currently we have a BigQuery native source for Python SDK [1].
> This can only be used by Dataflow runner.
> We should implement a Beam BigQuery source that implements
> iobase.BoundedSource [2] interface so that other runners that try to use
> Python SDK can read from BigQuery as well. Java SDK already has a Beam
> BigQuery source [3].
