Implemented ViaProxy bootstrap (#4201)

* Implemented ViaProxy bootstrap

* Applied requested changes to code

* Override indra settings to Java 17

* Removed explicit java source/target version

* Added ViaProxy artifact to build.yml

* Added ViaProxy artifact to pullrequest.yml

* Updated ViaProxy API usage

* Implemented floodgate support for ViaProxy

* Depend on stable ViaProxy release

* Initialize command manager and ping passthrough before Geyser#start

* Revert "Initialize command manager and ping passthrough before Geyser#start"

This reverts commit 39356071c4.

* Some ping passthrough improvements

* Merged code properly

* Updated ViaProxy API usage

* Implemented better command handling

* Updated ViaProxy and Geyser API usage

* Combine bootstrap and plugin into one class

* Minor code improvements

* Call Geyser shutdown on plugin disable

* Only call disable if Geyser was enabled once

* Don't send two shutdown done messages

* Use setter for enabled boolean
