typo - allow_values should be allowed_values in hot_guide.html

[Anne Gentle]

I found a typo in the Heat Orchestration Template (HOT) Guide (http://docs.openstack.org/developer/heat/template_guide/hot_guide.html).

In section "Restricting user input", below "Restricting user input", when it says "allow_values", it should say "allowed_values".

To fix, edit the doc/source/template_guide/hot_guide.rst file in the heat repo.
