Dean Troyer 2c5405ed5e Fix volume qos spec list
This has been sporadically failing in functional tests due to the way
the volume qos spec list command calls get_associations() for each spec.
When tests run in parallel occasionally a spec from another test is present
in the list returned and is deleted before the get_associations() call is
made, causing a NotFound exception.  We should just keep going when this
occurs.

* make v1 match v2
* add tests to ensure the exception is being caught and handled

Closes-Bug: #1687083
