    Description

      initializeGlobalShardingStateForMongoD has to be run on shardsvrs during initialization. Currently, this is triggered from the following places:
      1) In initAndListen
      2) In ShardServerOpObserver::onInserts when an insert of the shard identity document is observed.

      For FCBIS however, this does not work: On a new member that will undergo initial sync, point (1) will not find the shard identity document at all. Later, point (2) will not be triggered because FCBIS does not perform inserts like logical initial sync would.
      As a result, after FCBIS has completed, the shard is left with uninitialized sharding state.
