deployment-create raises an exception

[Yingzhe Zeng]

I tried to create a deployment with latest master code, by following command:
heat -d deployment-create -c 374f0a89-f5ca-43db-b96a-f1f720ddec11 -s 05fe8f38-5dbb-4028-abe1-2bd493b0ad47 -t NO_SIGNAL my_deploy_name

Then I got a exception like this:
Traceback (most recent call last):
  File "/usr/local/bin/heat", line 11, in <module>
    sys.exit(main())
  File "/usr/local/lib/python2.7/dist-packages/heatclient/shell.py", line 705, in main
    HeatShell().main(args)

    inputs = copy.deepcopy(source.get('inputs')) or []
TypeError: get() takes exactly 1 argument (2 given)

Seems at this situation, the type of "source" object is SoftwareConfig, and SoftwareConfig's "get" method only takes one argument.

    Fix deployment create error when using existing config

    We use an empty dict as config when deployment is created
    without a config. This fixes 'build_derived_config_params'
    to accept both SoftwareConfig object and empty dict.
