Implement: Compiling parameters for Resuming and re-running jobs

[jaserud]

Wiki with design has been created here

Detailed Description

• New POST endpoint in Workflow-Graph-Node /restart which will actually cover both re-run and resume cases
• This endpoint takes a RestartRequest: { runId: String, params: JSON }
• have an option to dry-run to be able to see what node would do with out actually doing it
• With this implementation if workflow_url, workflow_version, or the params Avro schema for a workflow-graph-node changes, that node cannot resume/rerun any runs from before the change.

Possible Implementation

Workflow-Graph-Node will

1. fetch the run
2. create a RunRequest with the workflow_url, workflow_version, sessionId (if it exists) and params (which is either the provided one or the params from existing run)
3. Verify workflow_url, workflow_versiom. params (validate with Avro schema) etc.
4. Start run
5. Add the new runId to its RUNNING queue
