      Add support to infer Avro schema from Hive table schema. Avro-backed tables can simply be created by using "STORED AS AVRO" in DDL statement. AvroSerDe takes care of creating appropriate Avro schema from Hive table schema, a big win in terms of Avro usability in Hive.

      Description

      Avro is well established and widely used within Hive, however creating Avro-backed tables requires the messy listing of the SerDe, InputFormat and OutputFormat classes.

      Similarly to HIVE-5783 for Parquet, Hive would be easier to use if it had native Avro support.
