Specify the following additional vars when syncing:
`ansible_ssh_host'`: The IP address of the host (for SSH)
`ansible_ssh_user`: `root` for SmartOS hosts, `ubuntu` otherwise
`ansible_inventory_hostname`: Hostname of the host
These additional variables allow for the format change in https://github.com/modcloth/tory/pull/64 which would break running plays against machines before DNS is setup.
