Migrate to new WHATWG URL standard

[molant]

We are using url.parse in quite a few places. While that method hasn't been deprecated, the recommendation is now to move to the new WHATWG URL API:

Note: While the Legacy API has not been deprecated, it is maintained solely for backwards compatibility with existing applications. New application code should use the WHATWG API.

Basically we need to replace:

import * as url from 'url';
cont parsedUrl = url.parse('http://domain'); 

with:

import { URL } from 'url';
const parsedUrl = new URL('http://domain');
