[to#issue-817]Add support for Clickzetta engine

Add clickzetta driver for data-diff

I am confused that I have clickzetta-connector == 0.8.59 in pypi, why the check is failed when download clickzetta-connector. The Download source is not pypi?

Setting a reminder to review this PR later this week!

Can you run poetry lock --no-update ? That will add the dependency to the lockfile

@sungchun12 I used our test account to test the corresponding ut, and they were all passed. It is currently in the external whitelisting stage and is expected to be ready on January 10. After it is available, we will run it through CI. Thank you so much

@idling11 Can you open source the code for the clickzetta-connector and its license? We'll need it for security review and submit issues if it's not working well with data-diff over time.

I'll wait until Jan 10 to provide fuller feedback.

OK, I have submitted it to the internal approval process of open source. I will give you the link after the approval is passed.
