Update jobs(v2) api-def

Fix some bugs of jobs(v2) in api-ref
1.The respense of "Show Jobs" is missing a "session_id" paramenter.
2.The files of job-create-request.json, job-update-request.json  have a
 unnecessary items "project_id"
3.The "project_id" is a public paramenter in freezer_action, so changed
its loaction in the files of job-get-response.json,job-list-response.json.
