title: How to export all firebase remote config keys and values?
body: <p>I want to migrate from existing firebase project to a new firebase project
  Issue is that I have a lot of remote config keys and values in my existing project
  Now I want to export all remote config keys and values then import to the new firebase project rather than writing everything over again in new project.</p>
  
  <p>Is there any easy way to do it?. </p>
