      Retryable writes now retries upon receiving a write concern error. It'd be nice to add tests to check this in our spec tests.

      Currently (per SERVER-34551) we can specify arbitrary error codes like the following shows:

      > db.adminCommand({"configureFailPoint":  "failCommand", mode: {times:1}, data:{errorCode:11601, closeConnection:false}});
> db.runCommand('serverStatus')
db.runCommand('serverStatus');
{
	"operationTime" : Timestamp(1525994518, 1),
	"ok" : 0,
	"errmsg" : "Failing command due to 'failCommand' failpoint",
	"code" : 11601,
	"codeName" : "Interrupted",
	"$clusterTime" : {
		"clusterTime" : Timestamp(1525994518, 1),
		"signature" : {
			"hash" : BinData(0,"AAAAAAAAAAAAAAAAAAAAAAAAAAA="),
			"keyId" : NumberLong(0)
		}
	}
}

      Can we extend the failCommand failpoint to return write concern errors? Something like the following:

      > db.adminCommand({configureFailPoint:  "failCommand", mode: {times:1}, data:{errorReply: {ok: 1, writeConcernError: {code:91}}, closeConnection:false}});
> db.runCommand('serverStatus')
{
    "operationTime" : Timestamp(1525994518, 1),
    "ok" : 1,
    "writeConcernError": { "code": 91,  "codeName": "ShutdownInProgress" }
    "$clusterTime" : {
        "clusterTime" : Timestamp(1525994518, 1),
        "signature" : {
            "hash" : BinData(0,"AAAAAAAAAAAAAAAAAAAAAAAAAAA="),
            "keyId" : NumberLong(0)
        }
    }
}
