No audit hook for sys.monitoring tools being cleared / freed #159379

Bug report

The sys.monitoring.register_callback audit hook fires when a sys.monitoring callback gets installed or uninstalled by a call to sys.monitoring.register_callback, but there's no audit hook that fires when a sys.monitoring callback gets uninstalled by a call to sys.monitoring.clear_tool_id or sys.monitoring.free_tool_id.

Is this intentional, or an oversight? It seems strange that there are two ways to uninstall a tool's callback, one of which fires an audit event and one of which doesn't.

I was hoping to use audit hooks to detect when a sys.monitoring tool was disabled in the middle of trying to do its work, but no audit event firing for sys.monitoring.clear_tool_id makes that impossible.
