Rewrite Ping Passthrough (#468)

* Fix ping passthrough on BungeeCord

* Initial implementation of direct ping passthrough

* Finished implementation of direct ping passthrough

* Remove test for something else entirely

* Fix standalone

* Add config option for ping passthrough interval

* Use GeyserPingInfo to reduce methods

* Add querying; modify ping passthrough

* Add separate config options for passthrough MOTD and player counts

* Convert all plugin bootstraps to use internal ping events to that other plugins can handle ping modifications

* Small changes

* Fix invalid packet spawm

* Add legacy ping passthrough option

* Fix BungeeCord

* Proper UUID for BungeeCord, thanks @theminecoder

* Update config version and messages

* Merge master... again

* Add missing javadocs and minor changes
