Subject: [PATCH] Add explicit VOLUME instruction for jetty image

Set a mount point for read-only root file system configurations.
Without the explicit mount point definition in the image, we were facing
issues on Amazon ECS, because the directory got mounted with different
ownership (root) and mode (0755).
