Allow setting forwarding mode separately for different servers

[Askarionn]

Requested Feature

PaperMC#1357

Why is this needed?

It is quite common to have a setup which includes both servers newer than 1.12 and older than 1.12. By allowing setting forwarding modes separately, we don't need to use the legacy forwarding mode all the time. Especially it is discontinued for newer fabric versions

Had to drop this commit since it caused unexpected issues in other areas of user connections. I'll look into getting this thoroughly tested as soon as possible.
