addresses #25030
We have observed that some UDFs(with bugs or imported some bad third-party
libs) could hang the runner and SDK harness processes in Samza portable mode.
Both runner and SDK harness processes are in a zombie state and have no data
processing in this case, however, the processes are not able to be shut down
although Samza runner provides some built-in timeout functionality.
This change will allow the users to set a timeout for closing a remote
bundle in Samza portable runner. Once the timeout occurred, the runner and SDK
processes will be shut down probably by Samza's built-in task timeout
functionality if enabled.
