Chef::Node::Mixin::DeepMergeCache#reset

Invalidate a key in the deep_merge_cache.  If called with nil, or no arg, this will invalidate
the entire deep_merge cache.  In the case of the user doing node.default['foo']['bar']['baz']=
that eventually results in a call to reset_cache('foo') here.  A node.default=hash_thing call
must invalidate the entire cache and re-deep-merge the entire node object.
