Description

Currently the {{AsynchIndexUpdate }} job which performs the indexing in background is run on every node in a cluster. This at times causes commit failures when running Oak in a cluster using Mongo MK. As merging of indexed content say Lucene is tricky to implement it would be better to restrict this job to run as a singleton in a cluster
