Change subject: IMPALA-9138: Classify certain errors as retryable
......................................................................


Patch Set 2:

Updated patch addressing Thomas' comments.

The most straightforward approach I could find was to make a dedicated 
MergeStatusProperties method in Status, and use that method on the 
overall_status tracked in QueryState. I decided to separate it out from 
MergeStatus because MergeStatus combines all the error message details of the 
two Status objects. If there are lot of failed fragment instances, the 
overall_status object could potentially get very large.

The only caveat is that overall_status is not idempotent. So it could initially 
be retryable, and then a later report could set it to non-retryable. 
Transparent query retries will have to be careful to wait for all fragment 
instances to complete before reading the properties of the overall_status.
