This allows users of axios inside `electron` to provide the [`net`](https://electron.atom.io/docs/api/net/) module as the http transport instead of using nodes http/https modules.  This gives a whole bunch of things to Electron users including automatic proxy resolution.

Add request field to AxiosResponse type definition

Update AxiosTransformer type in index.d.ts

Allow overriding the used transport

refactor: !isArray(obj) is always true

The first argument in `axios.interceptors.response.use` is optional, in the case that you just want to intercept an error.

Ex:

```ts
axios.interceptors.response.use(undefined, error => {
...
});
```

This would prevent tools like nsp to complain about a security issue from axios. It's something that got fixed in the package debug, and in order to benefit from that fix, it's necessary to upgrade to at least [email protected]

security: upgrade follow-redirects

Updating typings

Move window defined check before window.XMLHttpRequest check
