IMPALA-4988: Add query option read_parquet_statistics

This change adds a query option to disable reading Parquet statistics.
It provides a workaround when dealing with files that have corrupt
parquet statistics.

Note that Impala handles Parquet files affected by PARQUET-251 correctly
by ignoring statistics for anything but plain numeric types. This query
option is supposed to help with files affected by unknown or errors or
by errors that are yet to be made.
