[core] Public RESTful API

Outside of HUE, Oozie has a RESTful API that you can quickly deploy new workflows and coordinators to; however, there is no equivalent API inside the HUE environment. This causes unnecessary manual steps to import workflows through the Import UI each time a change is made to a workflow. It would be highly beneficial to expose a similar RESTful API for HUE that can be invoked to update the underlying HUE database when a new Oozie workflow has been deployed or updated from an automated process (i.e. Chef or Puppet).

Would like to propose something similar to the following:

Request
{
  "name":"{name}",
  "description":"{description}",
  "is_shared":"{is_shared}",
  "hdfs_deployment_directory":"{hdfs_deployment_directory}",
  "job_xml_file":"{hdfs_job_xml_file}",
  "workflow":"{xml workflow definition}"
}

Response
{
  "id":"{id}"
}
