In transitioning_replica_sets_jscore_passthrough suite we run a replicaset started as --shardsvr but not part of a cluster. This transition state is valid, and we should be able to execute commands.

The failing test is jstests/core/query/internal_rename_if_options_and_indexes_match.js which is doing an internalRenameIfOptionsAndIndexesMatch.

The task is to figure out if we can run these type of commands (accessing sharding state if running with --shardsvr) somehow during the transitional phase

Investigate too if the ShardingStateNotInitialized exception can be removed from sharded_cluster_util.py
