Issue DM-1653: Extend data loading script to support multi-node setup
Implement simplest use case for data loading with one or more worker database separate from czar database. Simplest means minimal functionality in what concerns access to workers, just assume for now that we can connect to every worker directly using regular TCP connection. It should be possible to just add a list of worker nodes as an option to loader script and send the chunks in some random order to the workers in that list. Of course chunks for different tables should end up on the same host, so some form of chunk management is needed (use for now whatever is defined in CSS doc on trac).
