preconnect to required origins
Problem: Consider adding 
preconnect
or 
dns-prefetch
resource hints to establish early connections to important third-party origins. For example to pre-connect google analytics: 
https://www.google-analytics.com
we should include 
rel
attribute with 
preconnect
value:
<link rel="preconnect" href="https://www.google-analytics.com" crossorigin>
