we need an option to store outputs

[dcb9]

add an option like this:

POST /job/ 
{
  ... ... 
  "storeOutput": boolean
}

then have to think about how to store the outputs. the easiest way is store it with JobStat See the code

As of #177 the output is logged to stdout along with other kala log handling.

Also, this looks like a duplicate of #138. Closing this one in favor of the prior issue.
