I'm currently using the python driver.
I keep a list of indexes per collection in memory using the IndexModel object.
Before starting any operation, I'd like to check that my indexes are in place.

I'd like to be able to ask the server if my indexes exist per collection. Or have `getIndexes` return a stable document that I can compare against.
