Tell commands - D2000 Thin client

The thin client will enter a "retirement" state and shut down after the specified time (seconds) has elapsed.
In the "retirement" state, the thin client will service existing connections, but will no longer accept new ones (i.e., it instructs the D2000 Server not to direct new connections from the web server to it).
This command allows you to schedule the shutdown/restart of the thin client so that it has as few connections as possible at the time of restart, and the restart affects as few users as possible.

If seconds=0, the thin client will go from the "retirement" state to the normal state (if it is necessary to cancel the scheduled restart).
