Function quiet? every return true

[ArmandoAssuncao]

@quiet - Time.now will always be smaller than quiet_timeout, so, if the sidekiq process is in quiet mode manually or the process does not die, the health check will continue return 200.

sidekiq_alive/lib/sidekiq_alive/server/rack.rb

Lines 53 to 55 in a531833

	def quiet?
	@quiet && (@quiet - Time.now) < SidekiqAlive.config.quiet_timeout
	end

validation should be like this:

@quiet && (Time.now - @quiet) < SidekiqAlive.config.quiet_timeout

With that, you will have 3 scenarios:

1. if time is smaller than quiet_timeout, returns code 200 with message Server is shutting down
2. if time is greater than quiet_timeout and alive? is true, returns code 200 with message Alive!
3. if time is greater than quiet_timeout and alive? is false, returns code 404 with message Can't find the alive key

To test, use the quiet button of sidekiq web.
