bigquery: job.wait inner backoff configuration is to slow

[idan3]

I'm using job.wait to determine when the job is complete. The internal configuration for the job.wait function is located within waitForQuery and is as follows:

backoff := gax.Backoff{
		Initial:    1 * time.Second,
		Multiplier: 2,
		Max:        60 * time.Second,
	}

It is a significant problem because the initial delay of 1 second is too slow when performing a large number of queries at a high rate. Can you please fix this or provide an option to modify this configuration?

Something like :

backoff := gax.Backoff{
		Initial:    80 * time.Millisecond,
		Multiplier: 1.1,
		Max:        60 * time.Second,
	}
