This PR implemented the migration framework, which contains the command
line interface to execute migration and helps to migrate data easily.
Please read README.md for more information about this framework.
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
