.extract_templates(config) ⇒ Object

Given an existing, fully-specified host configuration, count the number of hosts using each template, and return a map of template name to host count.

{"HOSTS"=>
 {"centos6-64-1"=>
    {"template"=>"centos-6-x86_64", ...},
  "redhat7-64-1"=>
    {"template"=>"redhat-7-x86_64", ...},
  "centos6-64-2"=>
    {"template"=>"centos-6-x86_64", ...}},
