Petclinic demo with Project Leyden premain optimizations (new workflow)

This spring-boot-leyden-demo repository intends to allow building a container image based on Project Leyden premain branch and the Spring Data JDBC variant of Petclinic, combined with the unpack-executable-jar.sh script, leveraging the proposed new Leyden terminal stage workflow. Spring AOT optimizations are enabled by default.

From within the spring-boot-leyden-demo folder, build the container image with:

./build.sh

And run the optimized runs with:

./run.sh
