title: Associated Public IP instead of EIP with terraform
body: <p>I'm trying to associate Public IP address to me instance instead of EIP but there's no "aws_public_ip" resource in terraform. </p>
  
  <p>I've reached limit of EIP's and I don't really need EIP - I can take advantage of public ip addresses.</p>
  
  <p>Does that mean it's not possible yet to attach public_ip in terraform?
  Have anyone been successful in attaching public ip to instance/interface using terraform?</p>
  
  <p>Thank you</p>
