Chef::Node::Attribute#combined_override

Accessing merged attributes.

Note that merged_attributes('foo', 'bar', 'baz') can be called to compute only the
deep merge of node['foo']['bar']['baz'], but in practice we currently always compute
all of node['foo'] even if the user only requires node['foo']['bar']['baz'].
