[ti-chi-bot]

This is an automated cherry-pick of #8331

What problem does this PR solve?

Issue Number: close #8330

What is changed and how it works?

When we handle the error of a stopped changefeed, the changefeed would be set to error state and retried by the owner. This behavior is unexpected. After this PR, TiCDC will not handle stopped changefeed errors and will just log them.

Check List

Tests

• Unit test
• Integration test

Questions

Will it cause performance regression or break compatibility?

Do you need to update user documentation, design documentation or monitoring documentation?

Release note

Fix a bug that causes a stopped changefeed to restart unexpectedly.

@ti-chi-bot: Your PR was out of date, I have automatically updated it for you.

At the same time I will also trigger all tests for you:

/run-all-tests

trigger some heavy tests which will not run always when PR updated.

If the CI test fails, you just re-trigger the test that failed and the bot will merge the PR for you after the CI passes.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the ti-community-infra/tichi repository.
