Description
When the catalog shard handles the setFeatureCompatabilityVersion command (via the run() member function in the SetFeatureCompatibilityVersionCommand class) it acquires a lock and eventually sends a setFeatureCompatabilityVersion command to all the shards. Since the catalog shard is also a shard, it will handle the command and attempt to acquire a lock again resulting in a deadlock.
