title: Completely disable Firebase/Analytics to stop console spam on app startup
body: <p>I've installed Google/SignIn cocoapod into my application (which I need to support GoogleDrive), but it depends on Google/Core which depends on FirebaseAnalytics. I don't want or need FirebaseAnalytics.</p>
  
  <p>FirebaseAnalytics spams the developer console with 8 lines of output when our app starts:</p>

  <p>(I had to add X to the URLs in the above output to get past stackoverflow's URL shortener blocker.)</p>
  
  <p>I tried setting FIREBASE_ANALYTICS_COLLECTION_DEACTIVATED to YES in my Info.plist, that removed 2 lines, but added another 2 lines to tell me that Analytics is disabled (FFS!).</p>
  
  <p>This spammed output makes it difficult for our developers to see any console output that is actually important. How can I disable it?</p>
  
  <p>(Failing that, a suggestion on how to get it outputting each line only once would be really welcome.)</p>
