The checkMetadataConsistency hook runs on a separate shell which does not authenticate.

In case a test enables authentication. The checkMetadataConsistency will error with Error.Unauthorized.

Before SERVER-70396 this behaviour was hidden behind the feature flag check which used to fail with "Unauthorized". However the try-catch would swallow the error causing the check to be skipped for the wrong reason.

After SERVER-70396 we will set Error.Unauthorized as TransientError

At the current state, the checkMetadataConsistency is always skipped in case authentication is enabled, causing a reduced test coverage.

This ticket is to make checkMetadataConsistency authenticate before running in case of enabled authentication. Similar to what is done in check_shard_filtering_metadata
