    Caveat: InfraValidator currently only recognizes SIGTERM signal as a
    graceful shutdown. Furthermore, SIGTERM can be handled only if the executor
    is running on the MainThread (the thread that runs the python interpreter)
    due to the limitation of Python API.

    When the executor is running on Kubernetes, SIGTERM is a standard way to
    signal the graceful shutdown. Python default behavior for receiving SIGTERM
    is to terminate the process without raising any exception. By registering a
    handler that raises on signal, we can effectively transform the signal to an
    exception, and we can reuse our cleanup code inside "except" or "finally"
    block during the grace period.

    When the executor is run by the local Beam DirectRunner, the executor thread
    is one of the worker threads (not a MainThread) therefore SIGTERM cannot
    be recognized. If either of MainThread or worker thread receives SIGTERM,
    executor will die immediately without grace period.

    Even if the executor fails to shutdown gracefully, external resources that
    are created by model server runner can be cleaned up if the platform
    supports such mechanism (e.g. activeDeadlineSeconds in Kubernetes).
