[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

+# Overview
+
+This folder contains several modules that build out bundles (i.e fat/uber jars) that enable hudi integration into various systems.
+
+Here are the key principles applied in designing these bundles
+
+ - As much as possible, try to make the bundle work with the target system's jars and classes. (e.g: better to make Hudi work with Hive's parquet version than bundling parquet with Hudi). This lets us evolve Hudi as a lighter weight component and also provides flexibility for changing these jar versions in target systems
+ - Bundle's pom only needs to depend on the required hudi modules & any other modules that are declared "provided" in parent poms (e.g: parquet-avro). 
+ - Such other modules should be declared as "compile" dependency in the bundle pom to actually get the shade plugin in pull them into the bundle. By default, provided scoped dependencies are not included
+ - Any other runtime dependencies needed by the bundle should specified in the `<include>` whitelist. New bundles also should follow the same style of explicitly whitelisting modules and shading as needed.
+ - Leave abundant comments on why someone is being included, shaded or even being left out.
+
+Please follow these when adding new ones or making changes.
