Allow a single node to process *-delete files of the eventual _queue folder

Duplicate *-delete files will be created after a GC run on each node of an HA cluster when the cluster-s3 template (or similiar is used) for the binarystore.xml.

Steps to reproduce the current behavior:
1. Setup HA with Eventual Binary Provider.
2. Watch the eventual/_queue folder of each node.
3. Delete artifacts from Artifactory and run the GC

Duplicate -delete marker files will be seen in the _queue folders

Example in the screenshot. Each side lists _queue folder content of each node.
