Hi developers, I want to introduce a command for cherry-picking PRs automatically.
When we releasing a minor version of Pulsar, we need to cherry-pick the bug fix PRs into the release branch. Cherry-pick a lot of PRs will take a long time and sometimes there has some conflict need to resolve. I want to introduce a cherry-pick command which is similar to the rerun test command to make the cherry-pick process automatically. Ideally, after merging a PR, just need to comment `/pulsarbot cherry-pick this pr into branch-2.6`, then it will open a new PR to merge into the `branch-2.6`. Open a new PR to do this will make that change also run the CI test in the release branch to ensure the branch can build successfully. And because the merged PR will cherry-pick into the release branch as soon as possible, we won't need to do the cherry-pick when we release a new minor version. That will reduce a lot of work for the committers. If you have any suggestions please let me know. Thanks, Yong
