Service-Level-Configs redone

[uaon]

SLC in its infancy was for storing configurations and scripts for purposes of our windows / linux servers. now its a mess of docker images, legacy scripts and a directory mess.

Some spring cleaning is in order.

• restructure the directory so its more in-line with current practices
• update the readme with relevant information, purge all else.
• remove the wiki items, we dont use that anymore.
• re-evaluate if mod configurations will be done via eggs or via json/yaml
• keep tracking on pterodactyl updates if/when they switch to yaml.

Restructure completed. Readme updated. Removed not-relevant wiki items and updated arma3 wiki entry. Mod configs will continue being done via json for now, potential for re-evaluation in the future.
