Updating URL parsing to WHATWG URL

[dresende]

@dougwilson I think we should update connection configuration URL parsing to use the new method as the previous is deprecated and I see some issues open about it (#2561), as well as myself hitting this problem with a more complex URL that url.parse is unable to process.

I can do this change right now but if we're going to do this, we should also increase the minimum node version that people can use with this module. What are your thoughts about it?

[dougwilson]

Oh, interesting. I mean, we could maybe use both, with the WHATWG when available, otherwise the old. What is the URL that you are having trouble with, BTW? Usually it is not very complex for this module, as there isn't a lot to it.

Ok, I will make a pull request supporting both. The URL has a password with a % on it. At first I tried to escape it, with no success using url.parse. The used the new URL approach and didn't even need to escape it. Just works.
