[Feature Request] Allow MOTD pings to hit back end servers, even if handling MOTD on a proxy

[KairuByte]

Is your feature request related to a problem? Please describe.
There are some plugins (or panels) that handle events like pings. One such situation I am running into is within the panel AMP. It allows you to put a server "to sleep" aka shutting it down, while continuing to broadcast as online. When a ping is detected, it will boot the server. This is currently not possible to do if the MOTD is handled on the proxy.

Describe the solution you'd like
An option on virtual hosts to simply query the back end server for it's MOTD when MiniMOTD handles a ping, even if it's response is completely ignored.

Describe alternatives you've considered
I can put MiniMOTD on the back end for some servers, but not all, such as Forge (non sponge), Mohsit, Magma.
