urllib3 has a new default behavior with PoolManager object creation

By default, from version urllib3=>1.25, urllib3 requires and validates certificates by default when using HTTPS (https://github.com/urllib3/urllib3/blob/master/CHANGES.rst#125-2019-04-22).
Set explicitly that we deactivate certificates validation with cert_reqs=`CERT_NONE`.
