Print the node definition before apply test

This makes it easier to tell which node definition is being evaluated
Because xargs -P doesn't do bash functions, some of the apply_test has
been moved into test_puppet_apply.sh. All the test snippets and test
output is being recorded in files in tools/opt, then catted for the
user.
