Create some pre-built configs

[NuroDev]

Currently there is a single example config file which serves as a great starting point, but it would be nice to have a few pre-built configs for people to drop in and go.

Some examples:

• One designed entirely around Docker and monitoring container metrics.
• Another designed to look pretty and having an overview of system metrics.

I agree, that is a good idea. Actually my plan was to have a Dockerfiles for a couple of popular linux distribution, with infrastructure installed for Real-world recepies section. And as you suggested, we might have a number of config files there to use - for test and documentation at the same time.

That way after each commit it would be easy to check visually that everything works as expected
