Support for multiple 'min-similarity-lines' values?

[jacebrowning]

Due to test fixtures and similar expected data payloads, I often have some duplicate test code.
I would like to be able to set a different value for min-similarity-lines in my test code than my application code.

Is this possible? Is there a way to nest configuration files?

I would consider just disabling the rule for test code, but that doesn't seem possible either (#214).

Right now this is not possible, not until #618 gets addressed.
