Hello Heat devs,

I've started doing some testing to find multi-engine bugs, and I
discovered that it's possible to create two stacks with the same name
when only a single heat-engine is running.

Here are the results of my tests:

Before I create a bug report about this, is it even necessary to enforce
unique stack names within a tenant?  Why don't we just key off of the
stack ID when possible and throw an error when it's not possible to look
up the stack by name?  This is how novaclient does it.

$ nova image-show F17_test
ERROR: Multiple image matches found for 'F17_test', use an ID to be more
