rhel-osp-director: Configuration errors resulting from tagging nodes with profiles should prevent the deployment from starting.

Environment:

instack-undercloud-2.2.5-1.el7ost.noarch
openstack-ironic-inspector-2.2.4-3.el7ost.noarch
openstack-ironic-conductor-4.2.2-4.el7ost.noarch
python-ironic-inspector-client-1.2.0-6.el7ost.noarch
openstack-ironic-common-4.2.2-4.el7ost.noarch
python-ironicclient-0.8.1-1.el7ost.noarch
openstack-ironic-api-4.2.2-4.el7ost.noarch

Steps to reproduce:
1. Deploy undercloud.

2. Assign profiles to nodes using this procedure: http://tripleo.org/advanced_deployment/profile_matching.html#examples-of-introspection-rules
 
3. Start a deployment with mispelling some profile name

Result:
Error: only 0 of 3 requested ironic nodes are tagged to profile control (for flavor control)
Recommendation: tag more nodes using ironic node-update <NODE ID> replace properties/capabilities=profile:control,boot_option:local
Error: only 1 of 2 requested ironic nodes are tagged to profile compute (for flavor compute)                                       
Recommendation: tag more nodes using ironic node-update <NODE ID> replace properties/capabilities=profile:compute,boot_option:local
1 nodes with profile ceph-storage won't be used for deployment now                                                                 
Configuration has 2 errors, fix them before proceeding. Ignoring these errors is likely to lead to a failed deploy.                
Configuration has 1 warnings, fix them before proceeding.                                                                          
Deploying templates in the directory /usr/share/openstack-tripleo-heat-templates     

Expected result:
The deployment shouldn't start.
