> Make single metastore call to fetch all column stats instead of separate call

>
> Currently HiveRelFieldTrimmer has the ability to fetch (and trigger cache)
> column stats in single call.
> HiveReduceExpressionsWithStatsRule on the other hand has to use column stats
> on demand, as a result it makes single call for each column.
> This should be moved after RelFieldTrimmer so that RelFieldTrimmer has all
> the column stats cached.
