Collect and verify role flavors fail

[Nikita Belov]

I have the following flavor with custom properties.

(undercloud) [stack@service-05 ~]$ openstack flavor show baremetal
+----------------------------+----------------------------------------------------------------------------------------------------------------------+
| Field | Value |
+----------------------------+----------------------------------------------------------------------------------------------------------------------+
| OS-FLV-DISABLED:disabled | False |
| OS-FLV-EXT-DATA:ephemeral | 0 |
| access_project_ids | None |
| disk | 0 |
| id | fd3ab787-9148-49e8-831c-f20e4bde22f0 |
| name | baremetal |
| os-flavor-access:is_public | True |
| properties | baremetal='true', resources:CUSTOM_BAREMETAL='1', resources:DISK_GB='0', resources:MEMORY_MB='0', resources:VCPU='0' |
| ram | 256 |
| rxtx_factor | 1.0 |
| swap | |
| vcpus | 1 |
+----------------------------+----------------------------------------------------------------------------------------------------------------------+

When I launch validation on TripleO-UI I get:
Task 'Collect and check the flavors' failed:
Host: undercloud
Message: Flavor baremetal has a resource class that is not offering exactly 1 resource
Flavor baremetal has to have scheduling based on standard properties disabled by setting resources:VCPU=0

Is it code ok? Why Maybe there is error with str/integer compare?
