> Add unified format interfaces and format discovery

> Key: FLINK-8558
> URL: https://issues.apache.org/jira/browse/FLINK-8558
> Project: Flink
> Issue Type: New Feature
> Components: Streaming Connectors
> Reporter: Timo Walther
> Assignee: Timo Walther
> Priority: Major
> Labels: pull-request-available
>
> In the last release, we introduced a new module {{flink-formats}}. Currently
> only {{flink-avro}} is located there but we will add more formats such as
> {{flink-json}}, {{flink-protobuf}}, and so on. For better separation of
> concerns we want decouple connectors from formats: e.g., remove
> {{KafkaAvroTableSource}} and {{KafkaJsonTableSource}}.
> A newly introduced {{FormatFactory}} will use Java service loaders to
> discovery available formats in the classpath (similar to how file systems are
> discovered now). A {{Format}} will provide a method for converting {{byte[]}}
> to target record type.
