Change syntax for adding/removing elabinelab attributes.
Made set-elabinelab-attribute set the attribute for all roles (nodes). Added a net command set-elabinelab-role-attribute to set it for a single role. Ditto for unset. The common case was setting a "global" attribute and it was tedious to give individual commands for boss, ops, fs, etc.
