Add support for schema registry module with support for multiple versions of schema

[abhioncbr]

Functionality / Module required for validation and transformation of a feed schema. Maintaining the versions of a schema is one of the basic requirement. Also, the schema should be easily accessible from various endpoints based on different methods.

Schema registry framework in future can be extensible for storing different vendors data-types mapping.

Schema module availability through grpc & thrift initially will be good. Later we can expose through rest api too.
