This commit adds the ability to specify whether the ansible_host and ansible_ssh_host variables should use 'name' inplace of 'interface_ip'. The primary use case for this, is if you want to access hosts using the instance name defined in OpenStack instead of the floating IP. This is usually when using a jump/bastion host.
