Hi,

I was working on fixing a bug in the API, and wrote a test that
unexpectedly failed.

Digging, I've discovered that it's currently a problem on how the
MongoDB storage handles its `resource' collection: you can't have 2
resource with the same id even if they came from 2 different sources.
Meaning that if you record:

  Counter(source='abc', resource_id='foobar')
  Counter(source='def', resource_id='foobar')

You'll end up with the 'source' field being overwritte because the
resource collection use resource_id as its MongoDB _id field.

So in the end, the request '/sources/abc/resources/foobar' returns
nothing.

This seems like a bug to me, because I easily imagine external systems
with different source values having resource-id that can collide,
because they're not UUID or the like.

Doug, what's your opinion this, and how to fix it?
