Provide a general way to handle and manage RIC message types (each type maps to an integer) that is aligned with 3GPP message types where appropriate. Right now (R0) message types are constants that are defined with integer values. However, there is a need to use symbolic/string names for the message types in the Dashboard and xApp Manager. Initial though: a more general (e.g., JSON) descriptor that can be translated into language specific header files.
