gpfdist: set default compression level to 3
The previous default compression level of 1 for gpfdist provides only
minimal data reduction while still incurring CPU overhead for compression.
This commit changes the default level to 3. This value represents a
better general-purpose trade-off, offering a more significant
reduction in network traffic for a modest increase in CPU cost.
This should improve performance for most network-bound ETL workloads
that use gpfdist with compression enabled.
