Review comment:
It's kind of strange that we validate the kafka version after the fact that
we have already selected some kafka version (after all `this` instance has
already a known Kafka version). This seems like either a duplicated logic or a
kind of unit test that is perform during the runtime. Maybe it could be
avoided/removed?

> Make Kafka version definition more flexible for new Kafka table factory

> Key: FLINK-10843
> URL: https://issues.apache.org/jira/browse/FLINK-10843
> Project: Flink
> Issue Type: Bug
> Components: Kafka Connector, Table API & SQL
> Affects Versions: 1.7.0
> Reporter: Timo Walther
> Assignee: Timo Walther
> Priority: Major
> Labels: pull-request-available
>
> Currently, a user has to specify a specific version for a Kafka connector
> like:
> {code}
> connector:
> type: kafka
> version: "0.11" # required: valid connector versions are "0.8", "0.9",
> "0.10", and "0.11"
> topic: ... # required: topic name from which the table is read
> {code}
> However, the new Kafka connector aims to be universal, thus, at least for 1.x
> and 2.x versions which we should support those as parameters as well.
> Currently, {{2.0}} is the only accepted string for the factory.
