Description

With SOLR-599 we added a new SolrJ client HttpJdkSolrClient which uses java.net.http.HttpClient internally. This JDK client supports asynchronous requests, so the Jdk Solr Client likewise can have async support. This ticket is to:

1. Extract from Http2SolrClient method

 public Cancellable asyncRequest(
      SolrRequest<?> solrRequest,
      String collection,
      AsyncListener<NamedList<Object>> asyncListener)

2. Implement on HttpJdkSolrClient

3. Add javadoc for both clients.

4. Add unit tests for both clients.
