ES: Implement online reindex for ElasticSearch

Browse Source 
Implement online reindexing for ElasticSearch based on the code for
Lucene online reindex.

Testing scenario:
 1. Start fresh Gerrit site with this patch
 2. Create account
 3. Verify data in ElasticSearch:
   curl http://localhost:9200/gerritaccounts_0004/
   curl http://localhost:9200/gerritaccounts_0004/_search
 4. Stop Gerrit
 5. Cherry pick change I77e1643cd1a7fbef9f4d2fa214823759188e9592
 6. Start Gerrit
 6. Wait for log message:
     Starting online reindex from schema version 4 to 5
 7. Verify state in ElasticSearch:
   curl http://localhost:9200/gerritaccounts_0005/
   curl http://localhost:9200/gerritaccounts_0005/_search

Entry for user account created in step 2 should have "elastic_online"
property with value "reindex work".
