Active_model_serializers: Add an option to remove log messages

[msathieu]

I would like an option to turn this
[active_model_serializers] Rendered ActiveModel::Serializer::CollectionSerializer with ActiveModelSerializers::Adapter::JsonApi (136.7ms)
log message of.

@MSathieu Of course. We should reference that in docs/general/logging.md along with the log subscriber and active support notifications api.

It's unclear to me if you want to

• set ActiveModelSerializers.logger = Logger.new(IO::NUL) or ActiveModelSerializers.logger = Logger.new(nil)
• just unsubscribe ActiveSupport::Notifications.unsubscribe(ActiveModelSerializers::Logging::RENDER_EVENT)
  
  
  
  • and maybe ActiveSupport::LogSubscriber.log_subscribers.delete_if {|subscriber| subscriber.instance_of?(ActiveModelSerializers::Logging::LogSubscriber) }
  
  

though I haven't tried these myself.

I want to set ActiveModelSerializers.logger = Logger.new(nil)

@MSathieu did that resolve your issue?

[msathieu]

@bf4 ActiveModelSerializers.logger = Logger.new(nil) doesn't works,
ActiveModelSerializers.logger = Logger.new(IO::NUL) raises an error,
but ActiveSupport::Notifications.unsubscribe(ActiveModelSerializers::Logging::RENDER_EVENT) works perfectly

@MSathieu Would you like to make a PR to improve the docs, especially based on how you went about looking for the info?

[msathieu]

I will do that.
