Originally, we designed to replicate the per-node storage options directoryPerDb and directoryForIndexes so that each node can use the replicated full ident correctly. This is not ideal as we are exposing per-node options to replication layer, which shouldn't be necessary. 

We modified the design to only replicate the unique tag part of the idents in SERVER-110477 and construct the ident on each node individually. We no longer need to replicate these two options now.
