DRA scheduler: use assume cache to list claims

Browse Source 
This finishes the transition to the assume cache as source of truth for the
current set of claims.

The tests have to be adapted. It's not enough anymore to directly put objects
into the informer store because that doesn't change the assume cache
content. Instead, normal Create/Update calls and waiting for the cache update
are needed.
