I don't think this is technically correct; according to the wireframes, a 'Role'
is a representation of a group of Heat resources from an overcloud stack - a 
Controller Resource, Compute Resource, etc.  Free nodes have no Role.

That's why I suggested this term after others objected to Role; it seems to me
that whatever term we use should have the world 'Resource' in it, in order to
make the correspondence clear.
