feat: make the cloudnet wrapper a java agent

[0utplay]

Motivation

Having the wrapper as java agent instead of a standalone application that boots the regular application resolves issues where e.g. the application depends on SPI to get some implementation, which was not possible with the current wrapper setup.

Modification

Re-designed the wrapper to be a java agent that is attached instead of a standalone application

Result

The wrapper is an agent and we can start taking a look into sponge support again
