Proposed signature for API call functions:

func GetConnections() (error, []byte)    //Implements /tapi/core/context/connection
func GetNodes() (error, []byte)          //Implements /tapi/core/context/topology/mcp-base-topology/node
func GetNodeEdgePoints() (error, []byte) ///tapi/core/context/topology/mcp-base-topology/node-edge-point

CLI calls to those functions: @m.stiemerling
