@leahecole could you have a look?

@m-strzelczyk, I see that a delay was added here possibly for working with eventual consistency. I hit a similar issue In python-monitoring and I added a retry to reduce the flakiness.

Thanks, I'll see how to apply this to those tests, they are really irritating :P

OK, the sleeps seem to have solved the problem with those tests. @leahecole can you review?

[m-strzelczyk]

@parthea can you perhaps give a review? I'd love to get this merged this week :P
