Add test coverage for overlapping methods and attributes machine_batch / chef_server / machine_options / image_options

[tyler-ball]

In https://github.com/chef/chef-provisioning/blob/4638bdf99e048452b5b80e06c118ba2a0a0132a3/lib/chef/provisioning/chef_run_data.rb and https://github.com/chef/chef-provisioning/blob/4638bdf99e048452b5b80e06c118ba2a0a0132a3/lib/chef/provisioning/recipe_dsl.rb we provide helper methods to define globals which merge with certain attributes. Unfortunately, there is not sufficient testing or documentation on how this is supposed to work.

How do the attributes in the machine_batch get merged down to the individual machines? What about actions? How does CP automatically batch individual machines?

This probably deserves its own EPIC

[hh]

Do we have an EPIC for this yet?

[tyler-ball]

@hh unfortunately not - we're working on non-provisioning stories for the foreseeable future

[hh]

I'm not sure what you mean by non-provisoning... non chef-provisoning?

[tyler-ball]

@hh Yes, non chef-provisioning work
