Following what have been done in the Naming/RescuedExceptionsVariableName cop in the rubocop repo, we should also handle the Rails version that use rescue_from:

class MyController < ApplicationController
  rescue_from MyException do |exception| # <= should be flagged with an offense
    # do something
  end
end

Should this cop read the configuration of Naming/RescuedExceptionsVariableName or have its own duplicated ?
