[OnceECClient][LinkisManager]Once job client obtains EngineConn information, it should use ticketId as the unique key

[peacewong]

What is the purpose of the change

Once you need to obtain the status information of the EC to determine whether the EC exits normally, but the current way to obtain it is through serviceInstance. Since the information is not unique by the IP and port, it will result in the acquisition of multiple EC information, resulting in an error. . In this fix, it is recommended to use ticketid to obtain, this is the unique key of UUID
