Port all templates to HOT

This change was generated and validated by running the following:

    make hot clean all validate-all

This converts all templates to be valid HOT.

Fn::Select is not converted in this change but this will actually
work with heat_template_version 2013-05-23. Fn::Select is converted
manually in the next change in this series.

This change also sets the heat_template_version to 2014-10-16 which
includes the list_join intrinsic functions used throughout these
templates.
