/**
* Returns an iterator of hosts to be used for a request call.
* Ideally, the first host is retrieved from the iterator and used successfully for the request.
* Otherwise, after each failure the next host should be retrieved from the iterator so that the request can be retried until
* the iterator is exhausted. The maximum total of attempts is equal to the number of hosts that are available in the iterator.
* The iterator returned will never be empty, rather an {@link IllegalStateException} in case there are no hosts.
* In case there are no healthy hosts available, or dead ones to be be retried, one dead host gets returned.
* Returns an {@link Iterable} of hosts to be used for a request call.
* Ideally, the first host is retrieved from the iterable and used successfully for the request.
* Otherwise, after each failure the next host has to be retrieved from the iterator so that the request can be retried until
* there are no more hosts available to retry against. The maximum total of attempts is equal to the number of hosts in the iterable.
* The iterator returned will never be empty. In case there are no healthy hosts available, or dead ones to be be retried,
