refactor(web/runner): Support pluggable job manager

This change introduces a new interface `JobManager` that is responsible
for communicating with the backend about the available jobs and updating
their status when the runner is simulating a job. This manager can be
injected into the `OpenDCRunner` class and allows users to provide
different sources for the jobs, not only the current REST API.
