Adds two new methods to `RestClient` that take a `Request` object. These
methods will allows us to add more per-request customizable options
without creating more and more and more overloads of the `performRequest`
and `performRequestAsync` methods. These new methods look like:
```
Response performRequest(Request request)
```
and
```
void performRequestAsync(Request request, ResponseListener responseListener)
```
This change doesn't add any actual features but enables adding things like
per request timeouts and per request node selectors. This change *does*
rework the `HighLevelRestClient` and its tests to use these new `Request`
objects and it does update the docs.
We publish javadocs to artifacts.elastic.co (and snapshots.elastic.co) for a while. This commit adds the link to them to the transport client, low level REST client, sniffer and high level REST client pages.
Closes#23761
It was brought up that our current client artifacts have generic names like 'rest' that may cause conflicts with other artifacts.
This commit renames:
- rest -> elasticsearch-rest-client
- sniffer -> elasticsearch-rest-client-sniffer
- rest-high-level -> elasticsearch-rest-high-level-client
A couple of small changes are also preparing the high level client for its first release.
Closes#20248
Using the infra that we now have in place, we can convert the low-level REST client docs so that they extract code snippets from real Java classes. This way we make sure that all the snippets properly compile. Compared to the high level REST client docs, in this case we don't run the tests themselves, as that would require depending on test-framework which requires java 8 while the low-level REST client is compatible with java 7. I think that compiling snippets is enough for now.
This commit converts the low level client and high level client chapters into two parts, which allows each high level client supported api to be on a separate page and show up in the index on the right.
The REST Client is split into 2 parts:
* Low level
* High level
The High level client has a main common section and the document delete API documentation as a start.
