> Similarly to https://issues.apache.org/jira/browse/BEAM-2677, we should be able to write
to avro files using {{AvroIO}} without specifying a schema at build time. Consider the following
use case: a user has a {{PCollection<GenericRecord>}}  but the schema is only known
while running the pipeline.  {{AvroIO.writeGenericRecords}} needs the schema, but the schema
is already available in {{GenericRecord}}. We should be able to call {{AvroIO.writeGenericRecords()}
with no schema.
