Run TestAMRMClient TestNMClient TestYarnClient TestClientRMTokens TestAMAuthorization tests with hadoop.security.token.service.use_ip enabled

All YARN test cases are running with hadoop.security.token.service.use_ip disabled. As a result few tests TestAMRMClient TestNMClient TestYarnClient TestClientRMTokens TestAMRMTokens cases are consistently failing because of unable to resolve hostname(see HADOOP-12687 YARN-4306 YARN-4318)

I would suggest to run tests with hadoop.security.token.service.use_ip enabled by default. And for the HA test cases which require mandatory disabling , change test cases as required by setting

conf.setBoolean(
        CommonConfigurationKeys.HADOOP_SECURITY_TOKEN_SERVICE_USE_IP, false);
    SecurityUtil.setConfiguration(conf);
