url.parse() deprecation warnings

[johlinco]

When using Contentful, we are getting the following error.

DeprecationWarning: url.parse() behavior is not standardized and prone to errors that have security implications. Use the WHATWG URL API instead. CVEs are not issued for url.parse() vulnerabilities. (Use node --trace-deprecation ... to show where the warning was created)

I believe that it is coming from the createClient function within Contentful.
