Review comment:
       This patch sounds good. But i have a question.  RetrySettings seems to 
support retry with backoff. The following retry mechanism could be moved to 
here as well.
   
https://github.com/apache/beam/blob/master/sdks/java/io/google-cloud-platform/src/main/java/org/apache/beam/sdk/io/gcp/spanner/SpannerIO.java#L1485
   
   Can that be done? Not as part of this patch. I could send out a PR as well 
after testing. That would clean up some code in SpannerIO as well

> Default commit deadline in Spanner is 1hr, which can lead to a variety of 
> issues including database overload and session expiry.
> Shorter deadline should be set with backoff/retry when deadline expires, so 
> that the Spanner database does not become overloaded.
