Before this patch, the controller will sequence send the probe request
in the same cluster, and the following nodes will be delayed if some of them
are blocking.

I have tested the new codes and it will parallel send the probe request,
and the failover also works well:

It's error-prone to test manually while changing the failover/migration, I have added an issue to improve this.
