Puppet::Functions.create_function(:'wmflib::inject_secret') do
  # Injects secrets in a data structure, recursively. It searches string values
  # containing secret(something), and swaps them with the content of the secret
  # parser function. This allows to define hiera with calls to secret() inline,
  # so that it doesn't need to be added to the private hiera repository but
  # to the public one instead. It also guarantees better access control to said secrets.
  # @param Hash datastructure
  # @return Hash the datastructure with the injected secrets
