=== camel-elasticsearch-rest-client

The Exchange header constants in `ElasticSearchRestClientConstant` have been
renamed to follow the Camel naming convention used across the rest of the
component catalog. The Java field names are unchanged; only the header string
values have changed:

[options="header"]
|===
| Constant | Previous value | New value
| `ElasticSearchRestClientConstant.ID` | `ID` | `CamelElasticsearchId`
| `ElasticSearchRestClientConstant.SEARCH_QUERY` | `SEARCH_QUERY` | `CamelElasticsearchSearchQuery`
| `ElasticSearchRestClientConstant.INDEX_SETTINGS` | `INDEX_SETTINGS` | `CamelElasticsearchIndexSettings`
| `ElasticSearchRestClientConstant.INDEX_NAME` | `INDEX_NAME` | `CamelElasticsearchIndexName`
| `ElasticSearchRestClientConstant.OPERATION` | `OPERATION` | `CamelElasticsearchOperation`
|===

Routes that reference the constant symbolically (for example
`setHeader(ElasticSearchRestClientConstant.SEARCH_QUERY, ...)`) continue to
work without changes. Routes that set the header by its literal string value
(for example `setHeader("SEARCH_QUERY", ...)`) must be updated to use the
new value (`setHeader("CamelElasticsearchSearchQuery", ...)`).
