Type system for Samza SQL and Support for types in UDFS
This checkin adds
1. Type system for Samza SQL. Previously Samza SQL was using Calcite's
relational type system. We need an intermediate type system that is specific to
Samza SQL so that we could support Beam SQL in future. This intermediate type
system also allows to provide typing to Samza SQL UDFs.
2. Java annotations for Samza SQL that allows us to discover the Samza SQL
UDFs easily and also provide users to configure name of the UDF, whether it is
disabled.
3. Initial support for adding types in Samza SQL UDFs. Right now we are not
using these types for validations. Future checkin will add that capability.
