This implements a restart-in-place mechanism via `exec()`. The logic serializes and re-establishes state: - The child processes do not lose their parent; the new endpoint instance maintains the exact same PID - In flight audit records are protected, and the new instance setups writing to the MEP file. A hot restart will be visible in the audit log file as the MEP shutting down and restarting. - A log record is emitted to the "normal" logs indicating that hot restart is happening - Until we have a proper MEP pid file, the only access to hot-restart an MEP is to send the process SIGHUP.
