Noop Run tasks are not set to fail_on_error = false

Not all custom changes are mentioned in results of fuel noop run.

It happens in case of several changes in the same time. Below described scenario is just for example (scenario from automated test)

Steps:
1) Deploy env
2) Make these changes:
- remove heat service on primary controller:
# pcs resource delete p_heat-engine
- rename role SwiftOperator -> SwiftOperator-new
- modify /etc/nova/nova.conf on compute
3) Run fuel task with --noop on target nodes:
# fuel2 env nodes deploy -e 1 -n 1 2 -f --noop
# Deployment task with id 13 for the nodes 1, 2 within the environment 1 has been started.
4) Wait for 'ready' state and check summary
# fuel deployment-tasks --tid 13 --include-summary

Expected result:
Three messages are in summary:
1) Pcmk_resource[p_heat-engine]/ensure', u'message': "u'current_value absent, should be present (noop)'
2) Keystone_role[SwiftOperator]/ensure', u'message': u'current_value absent, should be present (noop)
3) Nova_config[oslo_messaging_rabbit/amqp_durable_queues]/value', u'message': u'current_value <value>, should be False (noop)

Actual result:
message #2 is not found
Task swift-keystone is in pending state

Please note that required message occurs in case of single custom change (swift-keystone is ready):
[root@nailgun ~]# fuel deployment-tasks --tid 13 --include-summary --task-name swift-keystone
