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.
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..
