id may be used to identify the transaction in subsequent
[Read][google.spanner.v1.Spanner.Read],
[ExecuteSql][google.spanner.v1.Spanner.ExecuteSql],
[Commit][google.spanner.v1.Spanner.Commit], or
[Rollback][google.spanner.v1.Spanner.Rollback] calls.
Single-use read-only transactions do not have IDs, because
single-use transactions do not support multiple requests.
For snapshot read-only transactions, the read timestamp chosen
for the transaction. Not returned by default: see
[TransactionOptions.ReadOnly.return_read_timestamp][google.spanner.v1.TransactionOptions.ReadOnly.return_read_timestamp].
A timestamp in RFC3339 UTC "Zulu" format, accurate to nanoseconds.
Example: "2014-10-02T15:01:23.045123456Z".
