Symlinks testing
Symlink to a folder not under the workdir will fail.
docker build -t symlink-1 . && docker run -p 8889:8080 -v $PWD/mount-files/:/home/wiremock --name wm-symlink --rm symlink-1
http://localhost:8889/static - shows files which are shipped with the container
http://localhost:8889/symlinked - tries to access a file which is symlinked outside the root-folder and fails.
