Feat 106 jobs status paginate

[helen-m-lin]

closes #106

• Added new /api/v1/get_job_status_list endpoint for getting airflow job status
  • GET /api/v1/get_job_status_list: gets jobs with default offset=0, limit=25
  • GET /api/v1/get_job_status_list?limit={limit}&offset={offset}: gets jobs using limit and offset from query params
• Added /job_status_table for displaying job table result. This is used as a iframe by main /jobs page
  • Updated /jobs page to allow users to change default jobs per page and navigate through the pages
