Rest Client Reactive: Add reactive flavor for ClientHeadersFactory
Added reactive flavor of `ClientHeadersFactory` that allows doing blocking operations. For example: [source, java] ---- package org.acme.rest.client; import org.eclipse.microprofile.rest.client.ext.ClientHeadersFactory; import javax.enterprise.context.ApplicationScoped; import javax.ws.rs.core.MultivaluedHashMap; import javax.ws.rs.core.MultivaluedMap; import java.util.UUID; @ApplicationScoped public class GetTokenReactiveClientHeadersFactory extends ReactiveClientHeadersFactory { @Inject Service service; @OverRide public Uni<MultivaluedMap<String, String>> getHeaders(MultivaluedMap<String, String> incomingHeaders) { return Uni.createFrom().item(() -> { MultivaluedHashMap<String, String> newHeaders = new MultivaluedHashMap<>(); // perform blocking call newHeaders.add(HEADER_NAME, service.getToken()); return newHeaders; }); } } ---- Fixes quarkusio#20001
