[FEATURE] GraalVM

[lwluc]

Is your feature request related to a problem? Please describe.
To reduce the resource usage of the worker we should ahead-of-time compile our applications with GraalVM.

Describe the solution you'd like
We're compiling the worker to a native image using GraalVM (Docker multi-stage build maybe).
Also have a look at building a custom JDK distribution (jlink) for smaller target images.

Goal is to optimize resource usage and reduce startup time as well as memory consumption.

Additional context
By switching to GraalVM we can consider using Micronaut as framework.
