framework-config: improve configkey caching (#10513)

Browse Source 
Using a simple hyphen as a delimiter for config cache key can lead to ambiguity if the “name” field itself contains hyphens. To address this, a Ternary object of configkey name, scope and scope ID is used as the config cache keys.
