for security reasons, the docker image should run without root access

todo:

1. in CI: build binaries outside docker
2. pass binary to image
3. ship image with binary
4. use gcr.io/distroless/static:nonroot
5. verify if files/plugins work without these permissions
6. solve plugin build: should need to be removed from the startup, require load from folder instead and return error if any
