[OSTF]Platfrom test test_vanilla_two_cluster failed with timeout error

[Tatyanka]

Scenario:
On Centos:
            1. Create a Fuel cluster. Set the option for Sahara installation
            2. Add 1 node with "controller" role
            3. Add 1 node with "compute" role
            4. Deploy the Fuel cluster
            5. Verify Sahara service on controller
            6. Run all sanity and smoke tests
            7. Register Vanilla2 image for Sahara
            8. Run platform Vanilla2 test for Sahara

Error Message

The following tests have not succeeded, while they must have passed: [u'Sahara test for launching a simple Vanilla2 cluster (fuel_health.tests.platform_tests.test_sahara.VanillaTwoClusterTest.test_vanilla_two_cluster). Test status: failure, message: Time limit exceeded while waiting for polling cluster status to finish. Please refer to OpenStack logs for more details.']

hm... looks like we have no enough resources on Fuel QA labs for Sahara platform tests.

[Tatyanka (tatyana-leontovich)]

Just to be clear there is next value for memory on the slaves
SLAVE_NODE_MEMORY=6144
so if it is become "no enough resources on Fuel QA labs for Sahara " please, fill the separate issue to the fuel-devops with new value that should be there

It looks like a KVM virtual machine is used as the compute node. In order to fix the issue we should increase the timeout for cluster creation in OSTF. But we may encounter another issue: if we increase the timeout, we may get an authorization error because of the expiration time of a token. In this case the solution is simple: don't use a KVM VM as the compute node.

It was already fixed in another bug:
