[RFE] Simple UX for checking configuration variables

[hhorak]

Containers often accept various environment variables that in the end result in changed configuration of the daemon. If we have dozen of such variables, it should be the matter of just:

• running one function dozen times
• providing the function of how to check what configuration value is used by daemon, because this is very specific to the particular daemon.
  That's what I'd call simple UX.
