Enhancement of Config Property Metadata

At present, our system lacks metadata for the Config Records. We aim to enrich this by introducing a Metadata API. This API should provide access to specific properties associated with each record.

#### Desired Properties for Each Config Record:

1. **Full Name**: The complete name of the property.
2. **Current Value**: The existing value that the property holds.
3. **Default Value Indicator**: A flag or indication to signify if the current value is set to its default state.

By implementing this Metadata API, we can achieve better clarity and management of our Config Records.
