Allow input templates and imported custom types to be provided as URLs with Heat-Translator auto-detecting the type (file vs URL), and add necessary unit tests. Note, since for some test cases currently the required file does not exist on github, we temporarily use files hosted somewhere else. Once the patch is merged a follow-on patch will be submitted to fix that issue and use URLs of the new files that are submitted with this patch. Change-Id: I79c07c228d9d4de22f84ef384d46e3605b9a649e Closes-Bug: #1340748 Partially Implements: blueprint tosca-namespaces

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.
