With 0.72.0 it seems that MONGO_OPTIONS stopped working.

The file that loads this environment variable was last touched here: #12595

The environment variable is normally loaded here:
https://github.com/RocketChat/Rocket.Chat/blob/develop/packages/rocketchat-cors/server/cors.js#L18

Suspicion is change to module has effected the order this code is executed in. This needs to be executed very early in start up.

This seems very likely would effect other functionality in this file
