Review Comment:
I'm still working on this PR now, I found it's better to include this PR in
`1.8.0`. Because I believe jdbcStateStore and jdbcEventHandler always work
together.
During I test the `jdbcEventHandler`, I found some defects of
`jdbcStateStore`, such as: FLINK-34389, this comment
https://github.com/apache/flink-kubernetes-operator/pull/765#discussion_r1480012807.
It means if we includes `jdbcEventHandler` in this version we can ensure
they work well together. If we release the jdbcStateStore in this version, and
release jdbcEventHandler in the next version. We might need to change the
jdbcStateStore again in the next version. It's better to release a final
version for users, and it won't introduce any incompatibility problem.
So I'd like to increase this priority, WDYT?
Note: the prod code is done(you can help review if you are free), and the
progress of unit test and ITCase is about 40% and I will finish it asap..
