Completed blueprints should filter out "Obsolete" blueprints

[Matt Riedemann]

This is similar to bug 1447287 but not exactly the same.

Looking at http://stackalytics.com/?module=nova-group&metric=bpc&release=pike it shows 51 completed blueprints, but launchpad shows 50:

https://blueprints.launchpad.net/nova/pike

This is the difference:

http://stackalytics.com/report/blueprint/nova/hyper-v-spawn-on-neutron-event

https://blueprints.launchpad.net/nova/+spec/hyper-v-spawn-on-neutron-event

Note it's marked obsolete and implemented because it was fixed via a bug.

It looks like https://review.openstack.org/179146 is why it's considered a completed blueprint for Pike, because it was marked obsolete and completed within the Pike series timeframe, but it's not actually a valid blueprint, it was just fixed via a bug and marked obsolete.

So it seems stackalytics should ignore 'obsolete' blueprints even if they are marked as implemented. If a blueprint is obsolete because it was implemented by some other blueprint, then it should be superseded in launchpad, not marked obsolete.
