This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.
If we want to have a full picture of versions running in a cluster, we need to add a `_cat/plugins` endpoint. Response could look like: ```sh % curl es2:9200/_cat/plugins?v node component version type url desc es1 mapper-attachments 1.7.0 j Adds the attachment type allowing to parse difference attachment formats es1 lang-javascript 1.4.0 j JavaScript plugin allowing to add javascript scripting support es1 analysis-smartcn 1.9.0 j Smart Chinese analysis support es1 marvel 1.1.0 j/s http://localhost:9200/_plugins/marvel Elasticsearch Management & Monitoring es1 kopf 0.5.3 s http://localhost:9200/_plugins/kopf kopf - simple web administration tool for ElasticSearch es2 mapper-attachments 2.0.0.RC1 j Adds the attachment type allowing to parse difference attachment formats es2 lang-javascript 2.0.0.RC1 j JavaScript plugin allowing to add javascript scripting support es2 analysis-smartcn 2.0.0.RC1 j Smart Chinese analysis support ``` Closes elastic#4824.
