-spec info([node()]) -> cluster_info().
Gather classy:info/0 from a set of nodes.
The nodes don’t have to be in the same cluster.
WARNING: as a side effect of calling this function,
the current node will establish Erlang distribution connection to all nodes in the list.
While this won’t affect code using classy:nodes(connected) API,
it may confuse code using plain erlang:nodes().
