Expose Elasticsearch indexing via automation

It will be interesting to expose the following indexing operations via REST:

• Elasticsearch.Index with params:
  • without param: drop index + reindex all

    curl -X POST -H "Content-Type: application/json+nxrequest" -u Administrator:Administrator -d '{"params":{},"context":{}}' http://localhost:8080/nuxeo/site/automation/Elasticsearch.Index
    

  • with NXQL string: reindex matching documents
  • with a document: remove doc and children from index then reindex the doc + children

• Elasticsearch.WaitForIndexing with params:
  • timeout in second
  • a refresh flag to ask to perform a refresh once indexing is done

    curl -X POST -H "Content-Type: application/json+nxrequest" -u Administrator:Administrator -d '{"params":{"timeoutSecond": "3600", "refresh": "true"},"context":{}}' http://localhost:8080/nuxeo/site/automation/Elasticsearch.WaitForIndexing
    

–
Elasticsearch indexing operation are now available from automation in addition to the Admin center.
Using a REST call you can now:

• Re-index an entire repository
• Re-index document that match an NXQL query
• Re-index document and its children
• Wait for indexing and perform an index refresh
