This change refactors current implementation to determine key manager backend for cinder and nova, based on the following two points. - keymgr_api_class was deprecated a while ago. We can remove this parameter now. - We don't have to redefine the parameter in puppet-tripleo layer but we can use the parameter implemented in puppet-nova or puppet-cinder directly.
