Fix ConfigDebug for puppet host runs

Before pike we used to be able to add -e environments/config-debug.yaml
and that would give us debug logs for puppet. With the move to ansible
running puppet we lost this feature.

Let's make sure that the old ConfigDebug variable still works with
the ansible playbook-based deploy steps. With this patch and ConfigDebug
set to true, we correctly get the puppet debug logs:

TASK [debug] *******************************************************************
ok: [localhost] => {
    "(outputs.stderr|default('')).split('\n')|union(outputs.stdout_lines|default([]))": [
        "Warning: Undefined variable 'deploy_config_name'; ",
        "   (file & line not available)",
        "Warning: This method is deprecated, please use the stdlib validate_legacy function, with Stdlib::Compat::Bool. There is further documentation for validate_legacy function in the README. at [\"/etc/puppet/modules/ntp/manifests/init.pp\", 54]:[\"/etc/puppet/modules/tripleo/manifests/profile/base/time/ntp.pp\", 29]",
        "   (at /etc/puppet/modules/stdlib/lib/puppet/functions/deprecation.rb:25:in `deprecation')",
        "Debug: Runtime environment: puppet_version=4.8.2, ruby_version=2.0.0, run_mode=user, default_encoding=UTF-8",
        "Debug: Loading external facts from /etc/puppet/modules/openstacklib/facts.d",
        "Debug: Loading external facts from /var/lib/puppet/facts.d",
....
