Fail pre-deploy validation if some nodes failed introspection

[Sergii Golovatiuk]

Due to libvirt/vbmc issue introspection didn't happen so the status was as

(undercloud) [stack@undercloud-0 ~]$ openstack baremetal introspection list
+--------------------------------------+---------------------+---------------------+-----------------------+
| UUID | Started at | Finished at | Error |

However, overcloud deployment didn't take into account that 2/3 of nodes didn't pass introspection and there are no enough nodes to complete overcloud installation. So, overcloud deployment failed as with the following failed resource

 | resource_status_reason | resources.Compute: Resource CREATE failed: ResourceInError: resources[1].resources.NovaCompute: Went to status ERROR due to "Message: Unknown, Code: Unknown"

Expected result:
fail validation and don't start deployment

Actual result:
Failed deployment

Environment:
RHOS 13, tripleo master
