[FLINK-8101][flink-connectors] Elasticsearch 5.3+ (TransportClient) and 6.x
(RestHighLevelClient) support
## What is the purpose of the change
*The purpose of this PR is to add Elasticsearch 6.X support on top of the
RestHighLevelClient. Indeed TransportClient is now deprecated and will be
removed in 8.X. Also the hosted version of Elasticsearch often forbid the use
of TransportClient.*
## Brief change log
* First a set of changes are borrowed from #4675:
* Add createRequestIndex method in ElasticsearchApiCallBridge
* Add flink-connector-elasticsearch5.3 project
* Add BulkProcessorIndexer in connector-elasticsearch5.3 to convert
ActionRequest to DocWriteRequest
* Then on top of these changes and of being able to create a
RestHighLevelClient instead of TransportClient:
* Add createClient method in ElasticsearchApiCallBridge. As
TransportClient and RestClient have only the AutoCloseable interface in common,
this is what the method returns.
* Make ElasticsearchSinkBase agnostic to whether it is using a
TransportClient or RestClient by adding a createBulkProcessorBuilder method on
ElasticsearchApiCallBridge that the ElasticsearchSinkBase calls. Implement this
method on all bridges.
* Add flink-connector-elasticsearch6 project leveraging Rest Client while
all the other ones still use TransportClient.
## Verifying this change
This change added tests and can be verified as follows:
* Elasticsearch test base has also been reworked a little bit to leverage
it for testing the Rest client base implementation.
## Does this pull request potentially affect one of the following parts:
- Dependencies (does it add or upgrade a dependency): if you use the
elasticsearch6 project, this adds dependencies on elasticsearch 6
- The public API, i.e., is any changed class annotated with
`@Public(Evolving)`: no
- The serializers: no
- The runtime per-record code paths (performance sensitive): no
- Anything that affects deployment or recovery: JobManager (and its
components), Checkpointing, Yarn/Mesos, ZooKeeper: no
- The S3 file system connector: no
## Documentation
- Does this pull request introduce a new feature? yes
- If yes, how is the feature documented? docs & javadocs
