[RunConv][Back] Terminate a running pipeline

As a Data Preparation user with Runtime Convergence activated,
I want to terminate the pipeline execution of a running preparation (run currently in progress)
In order to save time and computing resources in case the run completion is not needed any more (e.g. I have done a run configuration mistake and I want to restart a new run with some configuration changes...)

Why?

From the run history page, we want to allow the user to terminate a preparation run, similar to the "stop pipeline" feature in Pipeline Designer.

How?

• Create a new TDP backend endpoint for Runtime Convergence mode
  • Stops the pipeline => Use endpoint from Pipeline API  TPRUN-248  API documentation
• Include IT creation for new endpoint
• Out of sope: legacy mode => frontend calls the existing legacy "cancel" TDP endpoint
• Document in API designer
• The user must have access to the preparation to kill a run (API returns 403 when user have not access to the preparation)
• API returns a 404 Not Found, if the run does not exist or associate to another preparation.

Acceptance criteria

• Integration test available

• Given a tenant with Runtime Convergence activated,

and a preparation with a running run

When calling TDP endpoint to terminate the preparation run

Then the pipeline is terminated, and the execution status is updated (KILLED received from Kafka)

• Scenario 2: runtime convergence mode (from https://jira.talendforge.org/browse/TDP-10033__)_
  Given a tenant with Runtime Convergence activated,
  and a preparation opened with a running run
  When the user opens the run history page and clicks on "terminate" action
  Then a confirmation modal is opened
  When the user confirms the termination of the run
  Then the run history entry is updated:
  • Status: Terminated
  • End time & time spent
