Test for pacemaker resources when disk is full

[Sergii Golovatiuk]

We made a change to Fuel with https://review.openstack.org/#/c/226062/

Since then pacemaker will stop resources when disk is almost full. However, it would be nice to write automation tests for such cases.

Test:
1. Check that all resources are running
2. Fill in space on partition
3. Check that all resources should be stopped
4. Make more than 10% space on that partition, and run command to clear the health issue:
   crm node status-attr <hostname> delete "#health_disk"
5. Make sure that all resources are started on this controller
