Missing debug trace in RemoteElasticsearchConnection.createTransportClient().
This is necessary in order to diagnose configuration problems, for example, see: LPS-97878

Steps to reproduce

1. Install a new Liferay instance
2. Install a Elasticsearch server (see: https://portal.liferay.dev/docs/7-2/deploy/-/knowledge_base/d/installing-elasticsearch )
3. Configure Liferay with REMOTE Elasticsearch configuration (see: https://portal.liferay.dev/docs/7-2/deploy/-/knowledge_base/d/configuring-the-liferay-elasticsearch-connector )
4. Execute a full reindex and verify search is working
5. Stop Liferay
6. Create a folder "log4j" inside of LIFERAY_HOME/osgi/
7. Copy attached files log4j.dtd and com.liferay.portal.search.elasticsearch6.impl-log4j-ext.xml into LIFERAY_HOME/osgi/log4j folder
8. Start Liferay and check log files
   • Expected behavior: a debug trace with elasticsearch remote configuration is written to log

     2019-07-04 11:29:57.519 DEBUG [Elasticsearch initialization thread][RemoteElasticsearchConnection:156] settings: {"client.transport.ignore_cluster_name":"false","client.transport.sniff":"true","cluster.name":"liferay-elasticsearch-pre","http.host":"_local_","monitor.jvm.gc.enabled":"false", ...

   • Wrong behavior: no debug trace is written to log file
