[HUDI-159] Redesigning bundles for lighter-weight integrations

- Documented principles applied for redesign at packaging/README.md
 - No longer depends on incl commons-codec, commons-io, commons-pool, commons-dbcp, commons-lang, commons-logging, avro-mapred
 - Introduce new FileIOUtils & added checkstyle rule for illegal import of above
 - Parquet, Avro dependencies moved to provided scope to enable being picked up from Hive/Spark/Presto instead
 - Pickup jackson jars for Hive sync tool from HIVE_HOME & unbundling jackson everywhere
 - Remove hive-jdbc standalone jar from being bundled in Spark/Hive/Utilities bundles
 - 6.5x reduced number of classes across bundles
