IMPALA-5500: Reduce catalog update topic size
Problem: IMPALA-4029 introduced the use of the flatbuffers serialization
libary for storing file and block metadata. That change reduced the
effectiveness of the Thrift compaction protocol (when
--compact_catalog_topic is used), thereby causing a 2X increase in
catalog update topic size when the compact protocol is used.
Fix: LZ4 compress the catalog topic updates before sent to the
statestore when --compact_catalog_topic is set to true.
Results: ~4X reduction in catalog update topic size
