Description

https://github.com/apache/beam/blob/master/sdks/java/core/src/main/java/org/apache/beam/sdk/io/TFRecordIO.java violates a few guidelines from https://beam.apache.org/contribute/ptransform-style-guide/ :

• Use of Bound and Unbound types: the Read and Write classes themselves should be PTransform's
• Should have one static entry point per verb - read() and write()
• Both classes could benefit from AutoValue

Basically, perform similar surgery like in https://github.com/apache/beam/pull/2149 but on smaller scale since this is a much smaller connector.
