Request for Java7

[ronnierap]

I would like to request support for java7 containers; some of the forge servers and plugins did not support java 8+ It can be a one-time spin-off of the java8 container (FROM openjdk:7u211-jre-alpine). I have a PR open: on Custom Server Packs; which would be great to make it onto a java7 branch.

In the future, I would not mind if it was not supported anymore, because these servers probably will not change the plugins. Plus the feature base you have currently for setting up containers is impressive and works very well for older servers;

I can definitely add support for that. I'll wait to confirm my feedback on your PR but will be quick to add after that.

I went ahead and created/pushed itzg/minecraft-server:java7. Verified using:

docker run --rm --entrypoint java itzg/minecraft-server:java7 -version
java version "1.7.0_221"
OpenJDK Runtime Environment (IcedTea 2.6.18) (7u221-2.6.18-1~deb8u1)
OpenJDK 64-Bit Server VM (build 24.221-b02, mixed mode)

Any chance this will be added? I'm trying to play Crash Landing.
