message: Add RecordInput documentation to tf.contrib.framework
  This fix tries to address the issue raised in 10622
  where the RecordInput is not available in the documentation.
  As was suggested in 10622, this fix exposes RecordInput
  to tf.contrib (tf.contrib.framework) so that
  docs could shown up.
  This fix fixes 10622.
