Description

Avro can infer the Schema for an Avro based PCollection by using the `withBeamSchemas` method, however if the user created a PCollection with Avro objects or IndexedRecord/GenericRecord, he needs to manually set the schema (or coder). The idea is to expose a method to easily get a Schema Coder from Avro objects or Schema and the user finally can set the Schema-based coder if it needs the PCollection to behavie like a Schema-based one.
