Apache Pinot

Hi folks, I <https://github.com/apache/pinot/pull/10321|opened this PR> in which I’m preparing the `pinot-spark-connector` package for Spark3 support. This is similar to what was done for the batch ingestion module to support different versions of Spark. Please take a look.

<@U011R2VMS4S> pinging you since you already did a similar work for the batch ingestion.
Also pinging <@UGRJA9TEH> as he reviewed multiple diffs for this package.
Thank you!

Thanks a lot for the contribution! I will take a look at it.

<@U01C8E0JMQV>: Just checking. Will this cover support for <https://github.com/apache/pinot/issues/10295|https> ?

<@U01C8E0JMQV> Does not look like. I started to add changed to support `https` . Let me know in case you are already working on it.

<@U02T028UEN7> you’re right, my change doesn’t include `https` support. Feel free to add it and let me know if you’d like a review. Thanks

<@U011R2VMS4S> please let me know if you have any comments or feedback on the PR.
