Current behavior

I am using mongoose plugin which depends on mongoose.connection
As I wrote in some other issues (#27 and #109) there was a problems after nest upgrade from 4 to 6 because you started to use createConnection() instead of connect().

Expected behavior

To have an option to get connection before models are initialized. Would be good to have it in MongooseModule.forRoot() or MongooseModule.forRootAsync() or somewhere else

Plugin that I am using is mongoose-id-validator which was using mongoose.connection to instance a model and search for a reference that I have in Document. I had to change this plugin after upgrading nest

My question is, is there some official way of getting connection that nest establish to mongo, after it is created, but before models are generated with MongooseModule.forFeature (plugins can't be applied on models that are already initialized), because plugin that I am using got as an option to provide a connection that should be used.

Minimal reproduction of the problem with instructions

What is the motivation / use case for changing the behavior?
