Bug 1388715

1. Proposed title of this feature request
Add task-group functionality to pulp-admin

2. Who is the customer behind the request?
Internal
 
3. What is the nature and description of the request?
pulp-admin can't handle task groups in pulp. However, getting information about them and ability to cancel them would be useful.
 
4. Why does the customer need this? (List the business requirements here)
1. Get progress information from current group tasks to monitor them from CLI
2. Cancel a group task if they are suspended in foreman and there is no opportunity to resume subtasks

5. How would the customer like to achieve this? (List the functional requirements here)
pulp-admin task-group cancel --task-group-id id
pulp-admin task-group progress --task-group-id id

6. For each functional requirement listed in question 5, specify how Red Hat
and the customer can test to confirm the requirement is successfully implemented.
Output of commands from q5 is consistent with Pulp API output
https://docs.pulpproject.org/dev-guide/integration/rest-api/tasks.html#task-group-management
 
7. Is there already an existing RFE upstream or in Red Hat bugzilla?
No

8. Does the customer have any specific timeline dependencies?
No 

9. Is the sales team involved in this request and do they have any additional input?
No 

10. List any affected packages or components.
pulp-admin-client-2.8.3.4-1.el7sat.noarch

11. Would the customer be able to assist in testing this functionality if implemented?
