Commit I46941e54a476c7cc8645cd1aff391c9c6c5434de added support for
blacklisting servers from triggered Heat deployments.
This commit adds that functionality to the remaining Deployments in
tripleo-heat-templates for the ExtraConfig interfaces.
Since we can not (should not) change the interface to ExtraConfig, Heat
conditions are used on the actual <role>ExtraConfigPre and
NodeExtraConfig resources instead of using the actions approach on
Deployments.
