Livy POST Sessions can not work with conf

[王峰]

Hello everyone , I have meet a problem about Livy-0.3 when I run `POST
/sessions` to create a new interactive spark session


here is the post body
```Content-Type: application/json; charset=utf-8
{
  "kind" : "spark",
  "proxyUser" : "root",
  "executorMemory" : "4G",
  "executorCores": 4,
  "numExecutors" : 4,
   "conf" :
{"spark.dynamicAllocation.enabled":false,"spark.shuffle.service.enabled":false}
}
```

However, I found that this Livy session  allocated all of resources in
Mesos UI as Pic shows

It seem like that `conf` did not worked but numExecutors , executorCores
and executorMemory worked well..

please help me  thanks...
