Configuration Entity

Configuration entities use the Entity API in order to keep configuration in the database.

Differences compared to Content Entity

1. Integrates with CMI API for exportability.
2. Doesn't have fields but uses properties instead.
3. Schema file (Content Entity uses hook_schema())
