[DISCUSSION] test connectors against Flink master in PRs

[Etienne Chauchot]

Hi all,

Connectors are external to flink. As such, they need to be tested 
against stable (released) versions of Flink.

But I was wondering if it would make sense to test connectors in PRs 
also against latest flink master snapshot to allow to discover failures 
before merging the PRs, ** while the author is still available **, 
rather than discovering them in nightly tests (that test against 
snapshot) after the merge. That would allow the author to anticipate 
potential failures and provide more future proof code (even if master is 
subject to change before the connector release).

Of course, if a breaking change was introduced in master, such tests 
will fail. But they should be considered as a preview of how the code 
will behave against the current snapshot of the next flink version.

WDYT ?
