[SPARK-18167] [SQL] Add debug code for SQLQuerySuite flakiness when
metastore partition pruning is enabled
## What changes were proposed in this pull request?
org.apache.spark.sql.hive.execution.SQLQuerySuite is flaking when hive
partition pruning is enabled.
Based on the stack traces, it seems to be an old issue where Hive fails to
cast a numeric partition column ("Invalid character string format for type
DECIMAL"). There are two possibilities here: either we are somehow corrupting
the partition table to have non-decimal values in that column, or there is a
transient issue with Derby.
This PR logs the result of the retry when this exception is encountered, so
we can confirm what is going on.
## How was this patch tested?
