Comment 0 for bug 1593975

Assume that there's a node with property 'auth_url' and attribute 'auth_token', then it is necessary to put them into 'outputs' section of a template:

  outputs:
    auth_token:
      value: { get_attribute: [ authorization_form, auth_token ] }
    auth_token:
      value: { get_property: [ authorization_form, auth_url ] }

But user did a mistake - he used the same name for both output items.

TOSCA parser parses in a wrong way. For item 'auth_token' it creates Output object with string value equal to '{ get_property: [ authorization_form, auth_url ] }'

So, there are two possible ways to resolve this issue:
 - abort on parsing saying output overriding is not allowed.
 - create two Output objects with correct TOSCA functions resolving and let user deal with it.
