Using logback with payara-micro

[Martin Charlesworth]

Hi, for anyone else struggling with using logback with payara-micro, I've created a github repo for this at https://github.com/grommitz/payara-micro-logback.

Thanks to Harry Chan who figured out how to do it first for log4j2. (https://github.com/hei1233212000/payara-micro-log4j2).
