Fix invalid syntax in HOT templates

This patch fixes invalid syntax in HOT templates where keywords
starting with uppercase characters are used (e.g. 'Type') in
the resources section. According to the HOT spec, though, those
keywords are all lowercase (e.g. 'type').

Change https://review.openstack.org/#/c/73580 in heat adds
stricter validation which makes the respective testcases fail.
