What problem does this PR solve?

• CDC sometimes returns TiKV errors to the user, which is confusing.

What is changed and how it works?

• Owner now checks whether updating service safepoint is successful, and, if not, throws the appropriate error.
• Wrapping TiKV errors with appropriate CDC errors.
