checkMetadataConsistency should check for orphan entries in the shard catalog.

An orphan entry can be:

• The collection is UNTRACKED* (doesn't exist on the global catalog), but there is one entry in config.shard.catalog.collections.
• The collection is UNTRACKED* (doesn't exist on the global catalog), but there are chunk entries in config.shard.catalog.chunks.
• The collection is TRACKED (exists in global catalog), and a shard owning no chunks has entries in config.shard.catalog.chunks (we need to filter out entries that remained for history field).

Scenarios where entries are acceptable:

• The collection is TRACKED and a shard owning no chunks has one entry in config.shard.catalog.collections.
• The collection is TRACKED and a shard owning no chunks has NO entry in config.shard.catalog.collections.

*Note: UNTRACKED here means unsharded collection living on the DB primary shard or literally leftovers and the collection doesn't exist.
