feat(stack): add NetData to the stack, no auth yet

[afolarin]

Started looking at server monitoring to the stack via NetData container #132

• docker compose with options to access the docker group (default I think is 999 but this may need to be a param)
• missing auth
  Ed.
  docs for nginx proxy setup.

Some security changes are probably needed (see comments). A general comment: it may make sense to have a separate stack (on a separate port, with a separate nginx instance) for these admin consoles. That would include kafka manager, portainer and netdata. This ensures that even if the RADAR stack is not working (e.g. one of the containers doesn't start), the dashboards are still active. If it is a single stack, Nginx will refuse to start if one of the containers is offline. It also splits up system privileged operations from regular operations, which is useful if the system has stringent user requirements.

It means that the kafka network would need to be external, to allow Kafka Manager to connect to the Kafka cluster.

yes agreed. I'll round-up work on adding this then look to adding another proxy dedicated for utilities.

LGTM. The breaking out of admin consoles can be done in a separate PR.
Thanks.

@blootsvoets suggestion a good one to refactor the monitoring services and route them separately

If only a few options are updated, You can also use command directive in docker-compose to supply the daemon opts listed here https://docs.netdata.cloud/daemon/#command-line-options to the container. In this case, it will be like -

...
command: -W set section option value -W set section2 option2 value
...

Coz i see most of the conf file is commented out anyways but the file is more than 40k lines
