Lazy-Queue-Mode is discontinued / the new default (RabbitMQ 3.12.X)

[fegbers]

Documentation

The library currently uses the x-queue-mode argument with the lazy value in two different ways:

1. DLX-Messages are always lazy
2. Custom configuration of the argument for classic queues (see examples)

=> Since support is discontinued / lazy is the new default, the feature should be declared as deprecated. Removal should be avoided to be backward compatible! A note about possible performance losses if the hard disk storage has less power should also be added:

Classic queue lazy and non-lazy modes no longer apply: classic queues v2 always behave very similarly
to the lazy mode in earlier release series: moving data to disk aggressively and only keeping a subset of data in memory
