Custom type for runner

[DormantCat]

Describe the new feature

We have a limited list of startup "cores" BUNGEECORD, VELOCITY, and a couple of other public ones, I suggest adding the ability to launch custom modules, this will increase functionality. Launching, for example, a Discord bot (written in java), Core system or something else

It is much more convenient to run 1 process through which everything is already managed

Why do you need this feature?

To start, manage processes, to remove restrictions in pre-installed versions!

Alternatives

Running processes in parallel with Cloud Net - but it's not convenient
