Can not use method ReactiveElasticsearchTemplate.execute because ReactiveElasticsearchTemplate.ClientCallback is not public

[kevinat]

org.springframework.data.elasticsearch.client.elc.ReactiveElasticsearchTemplate#execute(ReactiveElasticsearchTemplate.ClientCallback<Publisher<T>> callback)

Using this method cause compile error:

'org.springframework.data.elasticsearch.client.elc.ReactiveElasticsearchTemplate.ClientCallback' is not public in 'org.springframework.data.elasticsearch.client.elc.ReactiveElasticsearchTemplate'. Cannot be accessed from outside package

I noticed we move ClientCallback interface from interface ReactiveElasticsearchOperations into class ReactiveElasticsearchTemplate, but it seems we forgot adding the public modifier for the inner interface in class.
