Chef::EventDispatch::Base#msg

An uncategorized message. This supports the case that a user needs to
pass output that doesn't fit into one of the callbacks above. Note that
there's no semantic information about the content or importance of the
message. That means that if you're using this too often, you should add a
callback for it.
