Support for excluding variable from forwarding via forward_variables_form.

Some templates wants to forward all their parameters to the underlying
target except a select few they use. Previously they had to list all
the variables the underlying target supported which was error prone and
brittle if the underlying target is changed.

With this change they can just use the following:

  forward_variables_from(invoker, "*", ["my_extra_variable"])
  # my_extra_variable is not forwarded, all other variables are.
