Drago Rosson cae55d8ac1 Remove unconditional return of user_id
This removes a legacy backwards compatibility codepath. Pre-Icehouse
stacks that have resources which inherit from StackUser may require
manual cleanup after deletion, as their stack user may not be deleted.

This fixes issues with subusers using software config. Heat should not
attempt to delete the stack user if one had not been created before.
The code that this patch removes caused an ID to always be returned.
Additionally, it set the ID in the resource metadata whether a stack
user existed or not, making it impossible to tell if one existed only
from data within the resource.

upgrade:
- If upgrading with pre-icehouse stacks which contain resources that create
users (such as OS::Nova::Server, OS::Heat::SoftwareDeployment, and
OS::Heat::WaitConditionHandle), it is possible that the users will not be
removed upon stack deletion due to the removal of a legacy fallback code
path. In such a situation, these users will require manual removal.
