Preserve queue arguments when MaxRetry handler is used

[sharshenov]

2.12.0+ versions of Sneakers have MaxRetry handler incompatible with custom queue arguments.

class AwesomeWorker
  include Sneakers::Worker

  from_queue 'awesome',
             handler: Sneakers::Handlers::Maxretry,
             arguments: {
               'x-max-priority' => 10 # <-- this argument is ignored
             }

  def work(_)
    ack!
  end
end

Tests are failing for ruby-head like in master because of metric_fu-4.12.0

What is the state of this PR? We would really like to make use of the suggested improvement.

Sneakers now has a new home under https://github.com/ruby-amqp/kicks. May I ask you to re-submit this PR there? Thank you 🙏
