Rolls back a transaction.

>>> from google.cloud.gapic.datastore.v1 import datastore_client

>>> project_id = ''
>>> transaction = b''
>>> response = api.rollback(project_id, transaction)
Args:
project_id (string): The ID of the project against which to make the request.
transaction (bytes): The transaction identifier, returned by a call to
``Datastore.BeginTransaction``.
options (:class:`google.gax.CallOptions`): Overrides the default
settings for this call, e.g, timeout, retries etc.
Returns:
A :class:`google.cloud.proto.datastore.v1.datastore_pb2.RollbackResponse` instance.
Raises:
:exc:`google.gax.errors.GaxError` if the RPC is aborted.
:exc:`ValueError` if the parameters are invalid.
