[RA2] Expand Node labeling for different features

[rgstori]

now we just have generic and network intensive profiles - add other labels to describe node features.
it could be per-feature - e.g. add many labels, one per feature on the node
or it could be with profiles - e.g. add a single label, implying a set of multiple features on the node (e.g. hyper threading + rt kernel together).
