Add 4LW in Keeper, lgrq, for toggling

Why it matters

This feature allows administrators to enable or disable logging of all requests received by Keeper, providing better control over monitoring and debugging request handling.

How to use it

Use the 4LW command lgrq within Keeper to toggle the request logging state. This can be done by sending the lgrq command to the Keeper service to turn logging on or off as needed.
