Nodes manager

[tsafin]

Right now it requires a lot of manual massaging to create ECP connected nodes, so remote execution would work given its assumptions (i.e. particular controlling global name mapped between ECP client/servers).

We need to create something for easier connecting such remote Cache' nodes (i.e. registter IP, port, establish mapping, store metainformation to the central controllingnode).

It should be as simple as that:

do mapReduceMaster.RegisterNode(ip,port,namespace)

And all the namespace configuration should be done automagically.
