Options for "single-use", ReadOnly transactions, where Spanner chooses the read timestamp, subject to user-provided bounds.
This allows reading without blocking.
Because selection of the timestamp requires knowledge of which rows will be read, a single-use transaction can only be used with one read. See Client::Read() and Client::ExecuteQuery(). SingleUseOptions cannot be used to construct an application-level Transaction.
