> YARN-6125 implemented {{BoundedAppender}} and applied to the field {{diagnostics}} to
limit the diagnostic message's size.
> However, some code bypasses this limit. In {{RMAppAttemptImpl.rememberTargetTransitionsAndStoreState(...)}},
a local variable {{diags}} will finally be written into ZooKeeper if ZKRMStateStore is used.
> A simple fix is to also use {{BoundedAppender}} for the local variable.
