Task Revival endpoint

[youliangtan]

Feature

This will add a /revive_task endpoint to the current rmf_demos_panel api-server. This will enable user to revive a previously canceled/failed task.

How to test

• rmf_ros2: developing branch: feature/task-revival

Compile, then follow the steps below:

1. Run rmf_demos office world as normal

ros2 launch rmf_demos office.launch.xml

2. Open localhost:5000, then submit task list task_lists/office_tasks.json
3. Cancel Task: cancel Loop2 on the Web panel
4. Revive the Canceled Task:

curl -X POST http://localhost:8080/revive_task -d '{"task_id": "Loop2"}' -H "Content-Type: application/json"

minor: also I noticed this is still Cancel and not Revive

hi youliang, I was unable to replicate the revival based on the instructions. kept getting the [api_server]: /revive_task srv call failed message on the console, and tried to call the API with Postman as well, but the boolean received is still False. not sure what I might have done wrong but I rebuilt the entire ws just to be sure

@vallq Are you using the feature/task-revival branch from rmf_ros2? Also, take note that the task can only be revived if the task was canceled or failed.
