Improved state management

[amadeovezz]

NEW FEATURES:

• Return job dag and file dag
• Return completed jobs in save-config
• Return completed, planned and unscheduled files in save-config
• Actually implement get_config

CODE

• Refactor state management into a new class
• Config object stores state
• Run endpoint no longer calls find_buildable_targets - gets them from the config. This keeps targets consistent from calls to config and run
• Use snakemake to determine completed files/jobs instead of searching through the dag

OTHER NOTES

-We always generate a new config even if the params + available files are the same. We let snakemake determine this.

API CHANGES:

Modification to save-config

Now returns

success_json(
        {
          config_id: config.id,
          files: config.state['files'],
          jobs: config.state['jobs'],
          params: JSON.parse(workflow_params_json)
       }

where the state object looks like:

 {
        available_files: available_files,
        files: {
          completed: completed_files,
          planned: files_planned,
          unscheduled: unscheduled_files
        },
        jobs: {
          completed: completed_jobs,
          planned: jobs_planned,
          unscheduled: unscheduled_jobs
        }
      }

Modification to create-workspace

New param type: dag: obj.dag returns an adjacency list that represents the job dag (in json)
New param: file_dag: which is the file dag - also in json

New endpoint get-config
