heilukas requested to merge hazard_stage into develop May 12, 2017

Hazard Stage

Implements the hazard stage with an OpenQuake client for the OpenQuake 2 rest API.

Job Control

This MR improves job control by

Making return codes from workers more informative and correctly handling them on the client side
Correctly evaluating job statuses and and reflecting them in the gui
Persisting job statuses to the database

Tested with the remote ollinger worker on ramsiswin.ethz.ch and and OpenQuake running on localhost.

ToDo

Adapt the other workers (use the same code as for ollinger)
Indroduce timeouts / max. retries for the clients (model, hazard, risk)
Pass results between stages
