passing values via options file seems to skip sourceHost, sourcePort options

[mpcarl]

I am trying to pass in values via the options file. However, it does not appear that the options for sourceHost or sourcePort are used correctly. I made two modifications to the source...

options.js:
exports.readOptionsFile = function(opts) {
if (!opts.optionsFile){
return;
}
if (!fs.existsSync(opts.optionsFile)) {
return 'The given options file could not be found.';
}
var fileOpts = JSON.parse(fs.readFileSync(opts.optionsFile));
for (var prop in fileOpts) {
if (!opts[prop] && !exports.overrides[prop]) {
console.log("Copying property %s", prop);
opts[prop] = fileOpts[prop];
} else {
console.log("Skipping property %s", prop);
}
}
};

and es.js:
this.source = {
get: function (opts, path, callback) {
console.log("create GET source %s %s %s %s", opts.sourceUseSSL, opts.sourceHost, opts.sourcePort, opts.sourceAuth);
return create(opts.sourceHttpProxy, opts.sourceUseSSL, opts.sourceHost, opts.sourcePort, opts.sourceAuth, path, 'GET', {}, callback);
},

Running with the provided options.json:

node exporter.js -o test/data/options.json

produces this output:

That did it, thanks.
