Adds the setting 'spanner.copy_partition_query=true|false' to enable/disable the use of PartitionQuery for COPY TO STDOUT operations. Using PartitionQuery can improve the throughput when reading large amounts of data. However, the additional roundtrips and additional complexity of partitioning a query can be less efficient for smaller queries. This option allows the user to determine whether PGAdapter should try to use PartitionQuery or not. The default is true. Fixes #2224
