Adds Dynamic-config type (#5261)

- Refactors the config-store library to include a new dimension called 'configType' which allows for multiple stores.
- Refactors the config-store slightly to reflect the fact that it is indeed actually a daemon

These changes are tested and part of a larger set of changes of the 'zonal-isolation' feature
