The goal of this ticket is to test import and export collection using multitenancy and validating which case(s) work to enforce a strong contract for backup. The expectation is that :

• exportCollection (non-multitenancy) -> importCollection (multitenancy without feature flag) : ok
  • multitenancy no-feature flag to no-multitenancy should be OK too
• Exporting/Importing to and from a multitenancy+featureFlag replica set to one without multitenancy and/or without the feature flag should not work
  • Add a test to validate the behavior
• Add checks on specific fields in the properties returned by exportCollection
  • I.e. which fields are expected to have a tenant prefix
