List Data Center REST Endpoint

This ticket is part of the effort to add functionality of a Data Center Registry to the Program Service:
The Program Service scope is being expanded to also act as a Data Center Registry. Data Centers represent the Regional Data Processing Centers (RDPC) that ARGO will support a network of. Each program registered in the program-service must belong to a single Data Center. The Data Centers have various connection details that also need to be stored.

Add REST endpoint to fetch list of all Data Centers.
