                intended for use by pkglint Checker objects to provide hints as
                to how particular checks should be run.

                Keys are searched for first in the action, if provided, then as
                manifest attributes, finally falling back to the pkglintrc
                config file.

                The return value is a space-separated string of parameters.

                When searching for keys in the manifest or action, we prepend
                "pkg.lint" to the key name to ensure that we play in our own
                namespace and don't clash with other manifest or action attrs.
