refactor: Clio Config (#1544)

Implementation of new config definition + methods + UT

Steps that still need to be implemented: 
- Make ClioConfigDefinition and it's method to be as constexpr as
possible
- Getting User Config file and populating the values in ConfigDefinition
while checking for constraints on user values
- Replacing all the places where we fetch config values (by using
config.valueOr/MaybeValue) to instead get it from Config Definition
- Generate markdown file using Clio Config Description
