Converts both tools to use the ListUnifiedResources RPC instead of the ListResources RPC to improve performance. While there may only be marginal gains when listing the entire set of nodes, there are substantial improvements when filtering via predicate, labels, or search. tctl was also changed slightly to make use of server side filtering when tctl get node/foo is run. Prior to this change the entire node set was always retreived and tctl performed the filter client side if the user provided a hostname or UUID.
