Disable SSL peer/hostname verification for HTTPClient unless we've configured a trusted CA bundle like this: $config['http']['ssl_cafile'] = '/usr/lib/ssl/certs/ca-certificates.crt';

The previous state was failing on all HTTPS hits due to HTTP_Request2 library turning on the validation check but not specifying a CA file.
