There was inconsistency in the worker compose yaml for depends_on. The worker requires both db and redis, and in the default docker-compose.yml it was missing db, causing worker to crash on `docker-compose up`. In two other compose files for stacks, where depends_on was used for other services, I added it for the worker to match.
This patch optimizes the java-worker image;
- Use multi-stage build to separate the build-stage from the "deploy" stage
- Switch to the official Maven image, instead of manual installation of Maven.
The official Maven image is also based on the `openjdk` repository on Docker
Hub, which replaces the (now deprecated) `java` repository.
- Use `COPY` instead of `ADD` to follow best-practice
- Add `-XX:+UnlockExperimentalVMOptions -XX:+UseCGroupMemoryLimitForHeap` arguments
so that JAVA will take memory-limits into account
- Use a JRE base image for the final build-stage
This change brings the size of the final image down from 184MB to 87MB

The `--debug` option is deprecated and caused the result
service to not start:
result_1 | [nodemon] 1.14.7
result_1 | [nodemon] to restart at any time, enter `rs`
result_1 | [nodemon] watching: *.*
result_1 | [nodemon] starting `node --debug server.js`
result_1 | (node:20) [DEP0062] DeprecationWarning: `node --debug` and `node --debug-brk` are invalid. Please use `node --inspect` or `node --inspect-brk` instead.
result_1 | [nodemon] app crashed - waiting for file changes before starting...
This patch removes the `--debug` option, as it's not needed,
and no longer present in the other example stacks.
