Replace url-parse lib with native URL interface

[jonaswalden]

Engine specified to node >= 10. Should be no need for a lib to polyfill the URL interface or implement the legacy url.parse in a browser environment.

Thanks @jonaswalden.

https://github.com/amqp-node/amqplib/commit/7acbfd72330b835e1ffdad3daf78c222d1256142 details why url-parse was introduced in the first place. I suspect that now amqplib only supports node 10 and up, the standard url parser will be fine. Unless this isn't so, I'm in favour of this PR - the fewer 3rd party libs we import the better
