Description

It would be helpful to introduce a Version (or FlinkVersion) class were all the releases (including hotfix ones) are listed. This would be helpful to use in various places like tests, classes used to generate docs, etc.

It will become very handy, with the upcoming Upgrade story for Table/SQL.

 

Currently there is a `MigrationVersion` in `flink-core` but only keeps minor versions and is used in a limited scope.
