The conclusion of SERVER-89349  was to exclude any test that counts the documents present in the bucket namespace in case of balancer enabled.

Since many test were excluded, the goal of the ticket is to investigate whether another solution could be found for some of those excluded tests. Relaxing the check, or skip it in case of balancer enabled for some of those tests are all valid solutions. This would increase the test coverage.

The documents in the bucket collection are stored in a compressed format that allows faster queries. Having more documents as long as all the data are present is not necessarily a correctness issue.

After that, address the TODOs.
