Implement missing `/jobs/...` endpoints

[ThorodanBrom]

• GET /jobs
  • Lists all jobs
  • Can be scoped by provider to get info on all jobs run by particular provider
• GET /jobs/<job-ID>/results

  • Get result for a particular job

    DELETE /jobs/<job-ID> is also there, this allows for job dismissal, but none of the jobs we currently have can be dismissed easily

We'll try to complete this by Tuesday

• The PR is ready - https://github.com/datakaveri/ogc-resource-server/pull/222
• Actually for /jobs/{jobId}/results endpoint, the result will be the output in the jobs_table (as of now, all the outputs in the table are empty), in the process documentation it is mentioned that if a process is a sync one, the output of this jobs results endpoint should be like this --- The content of response SHALL be the requested process output in the requested output format. As of now (in S3PreSignedURL generation process, as it is the only sync process we have), there is no implementation to insert the process output into the output column in jobs_table.
