ConstantResolution: Should constants like ARGV be allowed?

[okuramasafumi]

I noticed that Lint/ConstantResolution cop treats ARGV as a constant and says we should fully qualify it. However:

::SomeGem::CLI.run(::ARGV)

This looks ugly. The name ARGV comes from tradition and we don't want to treat it as a "constant" while technically it is. The same applies to STDOUT, for instance.

So I suggest that we should discuss the default "Ignore" option value for that cop.
