Detailed bug description:
14 Nova-related Tempest tests failed on MOS 9.0 Mitaka #64

The list of failed tests:
test_snapshot_pattern
test_update_default_quotas
test_get_updated_quotas
test_create_server_when_cpu_quota_is_full
test_create_server_when_instances_quota_is_full
test_create_server_when_memory_quota_is_full
test_create_delete_image
test_delete_image_that_is_not_yet_active

test_get_image_for_alt_account_fails
test_get_metadata_of_alt_account_image_fails
test_set_metadata_of_alt_account_image_fails

Steps to reproduce:
1. Deploy OpenStack cluster with the following configuration: HA, Neutron VLANs, Cinder LVM, Swift (without Ceph).
2. Run full Tempest test suite using Rally tool (rally verify)

Expected results:
All tests passed

Actual result:
14-Nova related tests failed. Some of them are related to Nova Quotas, we are going to check them, but other related to metadata nad other features, and it looks like a regression issue.

Reproducibility:
100 %.

Workaround:
We don't know the workaround yet.

Impact:
All MOs users are affected, some Nova functionality doesn't work.

- Versions of components: MOS 9.0 Mitaka #64
- Reference architecture: HA, Neutron VLANs, Cinder LVM, Swift (without Ceph)
