title: How can I know the networkStatus of all queries in ApolloClient globally?
body: <p>I am trying to show preloader when a networkStatus is in-flight.</p>
  
  <p>I know that every query returns its own networkStatus, but in my application there are so many different queries. I want to have a way of handling all the networkStatus for all the queries, globally.</p>
  
  <p>What I'm wanting to know inside my code is the answer for: "Is there any query pending on the network?".</p>
