Master Issue: #16768 ### Motivation The problem has been discussed before in [#16792](https://github.com/apache/pulsar/pull/16792). And now I found that when creating a topic with large partition such as 500 on a cluster which already has many topics, it would frequently update zk node, put more pressure on zk, maybe result in zk node not available. Therefore I think we'd better fix this problem. Since the discussion in #16792 , there are 2 ways to enhance grant permission module. This is the second implementation, which I think is a better way to fix, and can have better compatibility with previous version. pulsar old version | | partition (e.g., persistent://public/default/mytopic-partition-0) | based topic (e.g., persistent://public/default/mytopic)| | ------ | ------ | ------ | | grant | only partition | grant all partition and then grant based topic | | revoke | only partition | revoke all partition and then revoke based topic (it doesn't matter if revoke partition failed) | | get | only partition | only based topic | | check | check partition and then check based topic | only based topic | pulsar new version | | partition (e.g., persistent://public/default/mytopic-partition-0) | based topic (e.g., persistent://public/default/mytopic)| | ------ | ------ | ------ | | grant | only partition | only based topic | | revoke | only partition | revoke based topic and then revoke partition (it doesn't matter if revoke partition failed) | | get | only partition | only based topic | | check | check partition and then check based topic | only based topic | ### Modifications do not grant permission for each partition ### Documentation <!-- DO NOT REMOVE THIS SECTION.

GitHub Actions provides separate quota for pull requests that are executed in a forked repository. The tests will be run in the forked repository until all PR review comments have been handled, the tests pass and the PR is approved by a reviewer. --> -- This is an automated message from the Apache Git Service.
