* feat: expose configuration property on CopyJob, ExtractJob, LoadJob, QueryJob (#1521)

* feat: expose configuration property on CopyJob, ExtractJob, LoadJob, QueryJob

Note for google-cloud-bigquery developers: This also refactors these classes so
that `_set_properties` does not modify the `_properties` dictionary in-place.
Doing so was also mutating the request object, making it difficult to debug
what request was _actually_ sent. Before this change, many tests hallucinated
that the request was always equal to the response.
