    Use scheduler hints in derived_parameters workflow

    Update the tripleo.derive_params.v1.derived_parameters workflow to use
    scheduler hints associated with a given role. The scheduler hints are
    used to identify overcloud nodes associated with the role, and take
    precedence over nodes identified by their profile/flavor. If a role does
    not specify any scheduler hints then the workflow falls back to matching
    nodes by profile/flavor.

    Add a tripleo.baremetal.v1.nodes_with_node_id workflow that searches
    for ironic nodes matching a node placement regex. This workflow is
    analogous to the existing nodes_with_profile workflow that searches
    for nodes that match a given profile.

    Add a tripleo.baremetal.get_node_id Mistral action that returns the node
    placement ID (e.g. "controller-0") for a given node, or None if a node
    ID is not defined. This is analogous to the existing get_profile action
    that returns the profile assigned to the node.

    Fix the 'message' published when a derived parameter sub-workflow fails
    so it just returns the sub-workflow 'message' and not the entire sub-
    workflow result. The 'message' portion is the only part that is meaningful
    to the user.
