title: Change cognito user pool user status
body: <p>Is it possible to change with my android App, Cognito user pool user status from FORCE_CHANGE_PASSWORD to CONFIRMED? or from RESET_REQUIRED to CONFIRMED?
  If yes which API call can I use?
  In fact, I imported users to Cognito and I don't find a way or any example on how to turn them to CONFIRMED status using my App.
  Thanks</p>
