This PR adds the following:

• Adding default values from the sample.env to use as fallback values in the docker compose files to remove the requirement of creating a .env file
• Monitoring deployment
  • grafana
    • kafka dashboard:
      
    • mongo dashboard
      
    • node exporter dashboard
      
  • prometheus
  • prometheus scrapers:
    • node exporter
    • kafka lag exporter
    • mongodb exporter

Works well for me! Easy to use. I did have to create the .env file but I didn't have to modify any values. Just wanted to clarify that since your pr description makes it seem like I wouldn't have to even do that.

Yeah a few variables are still required (compose profiles, docker host ip) but the goal is to have enough defaults where if it is used as a submodules a copy of a .env wouldn't be required as those variables would already be set.
