BigQueryHook.insert_job() returns job, not job_id

Executes a BigQuery job. Waits for the job to complete and returns job id.

states the method returns the job_id where it returns the job object.
Could be misleading if one expects a string. The full job details is much better as one can inquire on the errors or stats w/o having to fetch the job again.

BigQueryInsertJobOperator however does return the job_id value as documented.

Wondering if it would make sense to have a switch parameter in both to let user choose to return either job_id (default) or serialized job, in full or for a subset of keys.
