--------------------------------------
Summary: Eliminate the duplicate type check in creating
ControlRecord
Key: KAFKA-19068
URL: https://issues.apache.org/jira/browse/KAFKA-19068
Project: Kafka
Issue Type: Improvement
Reporter: Chia-Ping Tsai
Assignee: Chia-Ping Tsai
`RecordsIterator#decodeControlRecord` [0] do the type check and then
`ControlRecord` constructor [1] does that again ...
we should add a static method to ControlRecord to create `ControlRecord` with
type check, and then `ControlRecord` constructor should be changed to private
to ensure all instance is created by the static method
