This is an automatic backport of pull request #44862 done by [Mergify](https://mergify.com). ## Why I'm doing: Currently Follower FE will forward sql to Leader before verify blacklist, but every FE has its own blacklist, and this will cause two problems: 1. if one sql is in Follower's blacklist but forward to leader, this sql can be executed 2. For leader, because this sql is not in leader's blacklist, it will walk through every item in its blacklist which sometimes make cpu usage very high
