It should be possible to deploy Dictionary and Phi-regularizers only on the Master node (not on the remote NodeController node)

Currently in Network Modus Operandi all Dictionaries and all Regularizers will be deployed on all nodes. This should can be avoided for performance reasons.

• Phi-regularizers should be created only on the master node. Theta-regularizers shoudl be created on all nodes (including the master-node).
• message DictionaryConfig should have a flag, indicating whether to deploy this dictionary on the nodes. Master, in my opinion, should always have all the dictionaries.
