Don't deploy overcloud if any role is bound to deleted node profile

This change forces deleted mode profiles to be show as if they
were not set, thus preventing form to be submitted.
This change also prevents scaling with deleted node profiles
just in case someone manages to delete node profile
bound to deployed role (should be impossible).
