getters for ServerConnectionVars

[Beerlesklopfer]

Hallo to everyone,

I added to your code due to a need for my application dealing with the IoT Platform Cumulocity:

_/* G E T T E R S*/
inline const char* serverName() {
    return iServerName;
}

inline int serverPort() {
    return iServerPort;
}

inline IPAddress serverAddress() {
    return iServerAddress;
}_

Maybe it is useful to integrate to branch?
