This change will use the YAML SafeConstructor to safely load YAML data and auto-convert scalar types to strings to provide a consistent experience with AutoPkg's current behavior and data type expectations.
Basically this change will perform a very similar result as what I proposed in #911, however, it will only convert scalar types while preserving non-scalar types. Doing it this way should prevent any issues with current recipes.
I think, short term, this is a better option that what I proposed in #911.
Long term, I think updating the do_variable_substitution function (or update_data function as whole) would create the best experience as suggested by @jgstew here. This would give recipe writers more flexibility and allow more data types to be passed through AutoPkg steps.
