Upgrades the node environment to NodeJS 7.6.0. Functions can now use async/await and promises; they can return a promise instead of using a callback. The change preserves compatibility with the callback style. * Upgrade node environment to Node.js 7.6.0+ * Bump package version * Preserve compatibility for callbacks * Cleanup * Re-add hello callback example * Make sure not returning won't blow everything up * Update stock example with request promise
