Upgrading Red Hat OpenShift Container Platform to version 3.10 fails with error "error while evaluating conditional (item.kind == 'HTPasswdPasswordIdentityProvider'): 'dict object' has no attribute 'kind'"

Issue

• Upgrading the OCP control plane to version 3.10 via the upgrade_control_plane.yml Ansible playbook fails with the following error:

    1. Hosts:    master.example.com
       Play:     Upgrade master
       Task:     Install httpd-tools if needed
       Message:  The conditional check 'item.kind == 'HTPasswdPasswordIdentityProvider'' failed. The error was: error while evaluating conditional (item.kind == 'HTPasswdPasswordIdentityProvider'): 'dict object' has no attribute 'kind'
  
                 The error appears to have been in '/usr/share/ansible/openshift-ansible/roles/openshift_control_plane/tasks/htpass_provider.yml': line 2, column 3, but may
         be elsewhere in the file depending on the exact syntax problem.
  
                 The offending line appears to be:
  
                 ---
                 - name: Install httpd-tools if needed
