title: set/update firebase RemoteConfigs from CLI
body: <p>I wonder if Firebase CLI supports updating remote config params and conditions? How do I know if this is something planned to be added in future? As seen here (<a href="https://firebase.google.com/docs/cli#config-commands" rel="nofollow noreferrer">https://firebase.google.com/docs/cli#config-commands</a>) apparently, we can rollback to different versions but I can't figure out how to update the config template.</p>
  <p>Of course <a href="https://firebase.google.com/docs/reference/remote-config/rest/v1/projects/updateRemoteConfig#http-request" rel="nofollow noreferrer">Firebase rest API</a> supports that. But I really need it with CLI. Am I missing something?</p>
