Comment 9 for bug 1540374

Verified on MOS 8.0 + mu1 updates.

Scenario:
1) Upload network template to master node http://paste.openstack.org/show/492250/ (update interfaces names)
2) fuel network-template --env X --upload
3) fuel --env X deployment default
4) Check that transformation's order corresponds priority for node roles. Change priority and check that transormations also changes.
