Provide the ability to reference from the key store any value across the core entities

Customer would like the ability to reference the value of core entities like plugin parameters from a key value store as supposed to storing the values in the plugin themselves. This allows them to have a consistent configuration across environments (Dev, QA, Prod) and change the values of these parameters across environments without needing to change their config. Additionally if specific values change and are referenced by multiple fields, changing the value in one place will allow all instances that reference the value to be updated automatically without having to re-deploy configuration.
