[CoD2] Setup CoD2 with Docker

[Lonsofore]

Merge support for https://pterodactyl.io/ maybe?

(I'm not using it, but seems like the best free game panel on the market today, using docker)

Well, looks interesting, but:
1. What do you mean with "merge support"?
2. It's a panel to manage games in Docker containers, with a lot of dependencies, but... it isn't in Docker container. That's strange for me.

P.S. GUI is really nice
