Create openjdk-jdk14 mirror repository.

I believe it should be possible to use the skara mirror as base:
https://github.com/openjdk/jdk14

JDK 14 is slated to get released in March, but I'd need to get this added now as a stepping stone for JDK head builds. See: adoptium/temurin-build#1467

In April building will need to switch from openjdk-jdk14 to openjdk-jdk14u.

Can we confirm from Skara that the jdk14 repo is stable and won't be rebooted?

I'll create a skara mirror script so that we can test things out.
