title: Ansible copy ssh key from one host to another
body: <p>I have 2 app servers with a loadbalancer in front of them and 1 database server in my system. I'm  provisioning them using Ansible. App servers has Nginx + Passenger and running for a Rails app. Will use capistrano for deployment but I have an issue about ssh keys. My git repo is in another server and I have to generate ssh public keys on appservers and add them to the Git server(To authorized_keys file). How can I do this in ansible playbook? </p>
  
  <p>PS: I may have more than 2 app servers.</p>
