Subject: (#8575) Add loadyaml() function

This change adds a loadyaml() puppet function that takes a path to a
YAML data file and returns the contents as a Puppet variable.  There is
currently no validation of the contents of the file.

This commit is intentionally lacking unit tests because of time
constraints.
