Custom exception types for amended query job exceptions #1106
Description
I noticed in #1105 that we turn off type checking to add query_job and now debug_message properties to a GoogleAPICallError.
It'd be great if (a) there were some generic debug properties we could add to on the core GoogleAPICallError and/or (b) we had a custom exception type(s) so that folks can more easily discover debug_message and query_job.
