TheodoreLx opened a new pull request, #3554: URL: https://github.com/apache/celeborn/pull/3554
### What changes were proposed in this pull request? An EndpointVerifierMessageLoop is introduced to specifically handle RpcEndpointVerifier messages, and a separate thread is used to execute the EndpointVerifierMessageLoop. ### Why are the changes needed? RpcEndpointVerifier.CheckExistence is a high-priority message that needs to be processed first. In the original model, if the LifecycleManager's RPC message queue accumulates a large backlog, RpcEndpointVerifier.CheckExistence messages cannot be processed immediately, leading to numerous ShuffleClient initialization failures and causing task failures. ### Does this PR resolve a correctness bug?
