Upgrade the http library to resolve the Node x19 ECONNRESET error

Fix #104 by using a different http library. I think Axios would be a good library to use. 

We need to replace all usage of the `request` module with `axios`, and update the corresponding code in the RokuDeploy logic to work with `axios`. 
Make sure to run the device tests to make sure these all work. 
```
npm run test:device
```
