use metadata service for static/chef data, rather than /etc/profile.d/rancher.sh file

[AnalogJ]

if we populate all the chef node data into the metadata service we can query it using curl or https://github.com/kelseyhightower/confd (which is rancher compatible) rather than depend on an environmental file being available.

Check off services as they are converted to confd.
