NSB update

Refactored main NSB VNF classes accroding to class diagram

https://wiki.opnfv.org/display/yardstick/NSB+class+diagram

All the SampleVNFs have been separated and placed under
the SampleVNF class.

Added AutoConnectSSH to automatically create SSH conneciton on demand.

Added VnfdHelper class to wrap the VNFD dictionary in prepartion for
class-based modeling.

Extracted DpdkVnfSetupEnvHelper for DPDK based VNF setup.

Extracted Stats and other client config to ResourceHelper

Had to replace dict_key_flatten with deepgetitem due to Python 2.7
Jinja2 infinite recursion.
