Returns the service host and port for the given environment variable name.

@param serviceName the name of the service which is used as a prefix to access the <code>${serviceName}_SERVICE_HOST</code> and <code>${serviceName}_SERVICE_PORT</code> environment variables to find the hos and port
@param defaultHost the default host to use if not injected via an environment variable (e.g. localhost)
@parma defaultPort the default port to use to connect to the service if there is not an environment variable defined
Returns the service host and port for the given environment variable name .
