spzala 3a10532067 TOSCA: Create a test CLI program
This program provide a good usage to test the Heat-Translator tool on the
command line with expection of similar usage via Heat python client in near
future. The TOSCA hello world use case is implemented for quick testing
as well.

implements blueprint tosca-translator-cli-test-utility

"""
Test the heat-translator from command line as:
#python heat_translator.py
--template-file=<path to the YAML template>
--template-type=<type of template e.g. tosca>
--parameters="purpose=test"
Takes three user arguments,
1. type of translation (e.g. tosca) (required)
2. Path to the file that needs to be translated (required)
3. Input parameters (optional)
This should be only used for testing purpose. The proper use of
Heat-Translator tool is via python-heatclient once it made available there.
