//Takes a hostname, path, and msg to post to slack
var https = require("https");
exports.posttoslack = function(hostname, path, msg){
    return new Promise((resolve, reject) => {

        };
        var req = https.request(options, (res) => {
            resolve('Success');
        });
        req.on('error', (e) => {
            reject(e.message);
        });
        // send the request
