Update ServiceRepoService to List All of the NSLCM Status on the Service Characteristics

Currently, the Service Characteristics' NSLCM field only lists the last NSLCM update from the MANO. When multiple primitives are invoked, it would be helpful to list all of their status messages, not just the message regarding the last invoked primitive.

This improvement intends to list all status messages on an array, which will provide more information to the end user.
