Returns a Flowable that mirrors the source Publisher, resubscribing to it if it calls {@code onError}
(infinite retry count).

If the source Publisher calls {@link Subscriber#onError}, this method will resubscribe to the source
Publisher rather than propagating the {@code onError} call.
<p>
Any and all items emitted by the source Publisher will be emitted by the resulting Publisher, even
those emitted during failed subscriptions. For example, if a Publisher fails at first but emits
{@code [1, 2]} then succeeds the second time and emits {@code [1, 2, 3, 4, 5]} then the complete sequence
of emissions and notifications would be {@code [1, 2, 1, 2, 3, 4, 5, onComplete]}.
