Description

Currently, there is a large number of hard-coded references to the supported Flink versions (either the newest version, or a list of all supported versions). These should be condensed to a single source of truth to make upgrades easier and more robust.

Previously, we awked the list of Flink subdirectories, but this is not reliable because old, unsupported Flink versions can leave build directories behind. It would be better to read versions from a handwritten file.
