Description

The camel documentation states that there are two ways to acknowledge a Google pubsub message. They are "ackMode=AUTO" and "ackMode=NONE". If the mode is set to NONE, the document states that the "downstream process has to acknowledge explicitly". However there are no examples, or pointers on how to do that.

The unit tests also do not reflect this scenario. The AckModeNoneTest.java sets the ackMode to NONE, and checks if the message is redelivered, but it doesn't test how to acknowledge the message. This file AcknowledgeSync.java has the steps to acknowledge, but it's not clear how to do that within a Camel route. It seems to need an class called com.google.cloud.pubsub.v1.stub.SubscriberStub that is passed into it.
