Document production ready endpoints

[Aloren]

For spring boot there exists a nice doc: Production ready endpoints
Searching the same for spring-cloud-netflix leads to: Spring cloud netflix documentation. To find preconfigured endpoints you need to use search by word endpoint -- not very convenient.
And still /archaius endpoint is missing from this doc. :(
It would be nice to have page with preconfigured endpoints for this project as well. What do you think?
Thanks

Opened #4598 with a page for the current Eureka actuator/status URLs and the server dashboard plus /eureka API.
