Title: (#2157) Make facts_dot_d compatible with external facts

Since facts_dot_d will eventually be removed and replaced by
external facts, warn users who are using a ttl on their external
facts that this feature will not be in Facter external facts.

Provide a link to a page explaining how to cache fact values
without the ttl functionality.
