Rally Sahara test not working on scale

[Dina Belova]

create_and_delete_vanilla_cluster scenario is failing on scale.

Task 6cd5f0fa-4c98-4c1b-9a63-efd996bb5278: failed

InvalidBenchmarkConfig: Input task is invalid!

Benchmark SaharaClusters.create_and_delete_cluster[0] has wrong configuration
Benchmark configuration:
{'runner': {'type': 'constant', 'concurrency': 1, 'times': 2}, 'args': {'workers_count': 0.333333333333, 'flavor': {'name': 'm1.medium'}, 'hadoop_version': '2.4.1', 'plugin_name': 'vanilla'}, 'sla': {'failure_rate': {'max': 0}}, 'context': {'sahara_image': {'username': 'ubuntu', 'image_url': 'http://sahara-files.mirantis.com/mos60/sahara-juno-vanilla-2.4.1-ubuntu-14.04.qcow2', 'hadoop_version': '2.4.1', 'plugin_name': 'vanilla'}, 'users': {'users_per_tenant': 1, 'tenants': 1}, 'network': {}}}

Reason:
 Invalid scenario argument: 'workers_count is 0.333333333333 which hasn't int type'

After https://gerrit.mirantis.com/#/c/38689/1 was proposed, tests are still failing, and that's the only result:

[Nikita Konovalov (nkonovalov)]

The issue is not reproducing anymore after the template engine was fixed not set 0.333 compute count.

[Dmitry Mescheryakov (dmitrymex)]

Setting to invalid, as that is a more proper status for bugs which could not be reproduced any more
