When KieServicesClient  fails to connect to KieServer,  LoadBalancer  is invoked to check availability of server like the following.

[2019/01/24 18:19:38.411] [pool-1-thread-1] [DEBUG] (LoadBalancer.java:149)                  - Starting to scan if any of the failed endpoints is back online 
org.kie.server.common.rest.NoEndpointFoundException: No available endpoints found

	at org.kie.server.client.KieServicesFactory.newKieServicesClient(KieServicesFactory.java:101)
	at com.sample.rules.test.KieServerRestClientTest.connectionFailureTest(KieServerRestClientTest.java:55)


 But after that, the thread used by LoadBalancer remains until termination of client application as  LoadBalancer.close()  is not called.
