The Docker image cannot accept CMD or flags
Currently, the image is not able to accept any CMD entry or any command line flags passed with the `docker run` command or passed via the `command:` entry in Docker Compose yaml files.

The only way to pass flags is to include them in the Dockerfile `ENTRYPOINT` layer, like so:

```
ENTRYPOINT ["/bin/sh", "-c", "./xmrblocks --enable-json-api --enable-autorefresh-option --enable-emission-monitor --deamon-url=node2.sethforprivacy.com:18089 --enable-pusher"]
```

If you attempt to pass via CMD layer, the image fails to start, like so:

```
CMD ["--enable-json-api", "--enable-autorefresh-option", "--enable-emission-monitor", "--enable-pusher"]
```

And when passing flags via `docker run`, the flags are simply ignored:

```bash
docker run -it -v "/var/lib/docker/volumes/node_bitmonero/_data/.bitmonero:/home/monero/.bitmonero" -p 8081:8081 xmrblocks --enable-emission-monitor
```

Honestly I'm not sure how to resolve this, as every other executable I've containerized properly handles CMD, like monerod and p2pool:
