When running the script to update the Wordpress DB to point to the DNS name of the RDS instance it fails because the instance's meta data is not available without a token on newer EC2 instances.
E.g.: curl http://169.254.169.254/latest/meta-data/public-hostname -> 401 Unauthorized
Instead get token first and then use the token to fetch meta data.
