Description

Via SLING-7754, a JCR Resource-backed queue [0] implementation was developed for usecases where a queue processor wasn't required, ResourceQueue implementation is currently PASSIVE.

Given above, it is not possible to leverage ResourceQueue as a queue.provider for DistributionAgents created via ForwardDistributionAgentFactory [1].
This issue aims to add an "Active" variant of Resource backed queues and provide it as an option for ForwardDistributionAgentFactory.
