Chef-Solo handling for replicaset databags

[cjhubert]

Just starting off, want to say I'm definitely open to discussion on this pull request as I want to make sure I'm not suggesting any changes that reduce quality. I'm also not able to test this with chef-server, only chef-solo.

Right now, I'm unable to create a replicated, sharded cluster using chef-solo. When trying to start up the first mongod server, it errors out with the following Chef output:

You can see the complete example of how I'm trying to create the cluster in my MongoDB Cluster repo. It's quite possible I'm just using chef-solo-search improperly to create the information for the nodes, so please let me know if I am.

When using the change in this pull request, all the nodes come up successfully and look configured properly. The mongos server:

mongos> sh.status()

  sharding version: {
    "_id" : 1,
    "version" : 4,
    "minCompatibleVersion" : 4,

}
  shards:
    {  "_id" : "rs_default",  "host" : "rs_default/d0:27017,d1:27017,d2:27017" }

    {  "_id" : "admin",  "partitioned" : false,  "primary" : "config" }

        foo.bar
            shard key: { "baz" : 1 }
            chunks:
                rs_default  1
            { "baz" : { "$minKey" : 1 } } -->> { "baz" : { "$maxKey" : 1 } } on : rs_default Timestamp(1, 0)
