Modify Program DTO so all Program REST endpoints include some Data Center Information

[joneubank]

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.

As a result of the changes in #413, Programs now include a Data center and some of the Data Center information should be included in the Program entity when they are returned in any REST endpoint. This means we want to update the Program DTO to include the following properties of the Data Center:

• id
• name
• short name
• ui url
• gateway url

These properties can be provided nested in an object under the property name dataCenter:

{
  ...
  "dataCenter": {
    "id": "",
    "name": "",
    "shortName": "",
    "uiUrl": "",
    "gatewayUrl": "",
  }
}

These changes will be seen in several endpoints, including:

• CreateProgram
• UpdateProgram
• ListPrograms
• GetProgram
• List Data Center Programs (includes a list of programs, each program should contain this information)
