work with apache2 cookbook instead of breaking

[dmlb2000]

This adds a recipe to include if the box happens to also include the apache2 recipe somewhere, set the attribute node[:cobbler][:include_apache2] to make it setup the apache2 cookbook correctly to work with cobbler.

Hi @dmlb2000 , sorry for missing your PR here. I've been arguing with the Apache2 cookbook to merge your PR and am finding it to be a very painful cookbook to test with our test-kitchen for a few reasons:

• Ubuntu 14.04 support has been dropped
• By default it enables (and I can't find a way to disable without a second Chef converge):
  • mod_python which is incompatible with mod_wsgi
  • mod_authz which then causes all the Cobbler bits to not serve with an HTTP 403

I've pushed my attempt to get this to work with Ubuntu 16.04 to the branch dmlb2000-work_with_apache2_cookbook. Do you see what I'm missing in your use of the Apache2 cookbook?
