cannot inform user balance leader task is failed

[HarrisChu]

before we move balance leader to job manager, it is synchronous.
if balance failed, user gets the error message, and could run balance leader again.

but from v3.0, user should check the job status by themselves.

E20220304 01:57:14.036036  5068 MetaJobExecutor.cpp:31] partiton failed to transfer leader

balance leader failed.

[HarrisChu]

it's OK if user run balance leader again and the job is succeeded.

Will be fixed later, show job id will print the failed reason
