Add a new node type for logging

Browse source 
Changed the cluster framework scripts by adding a new Bro node type
for doing logging (this is intended to reduce the load on the manager).
If a user chooses not to specify a logger node in the cluster
configuration, then the manager will write logs locally as usual.
