Log context

Log “{} deleting index” classname is MetaDataDeleteIndexService.java
We extracted the following from Elasticsearch source code for those seeking an in-depth context :

 
        final IndexGraveyard.Builder graveyardBuilder = IndexGraveyard.builder(metaDataBuilder.indexGraveyard());
        final int previousGraveyardSize = graveyardBuilder.tombstones().size();
        for (final Index index : indices) {
            String indexName = index.getName();
            logger.info("{} deleting index"; index);
            routingTableBuilder.remove(indexName);
            clusterBlocksBuilder.removeIndexBlocks(indexName);
            metaDataBuilder.remove(indexName);
        }
        // add tombstones to the cluster state for each deleted index
