1. Proposed title of this feature request
[RFE] print applied filter on task export


3. What is the nature and description of the request?
There are different filters, some are default, some are configured using ENV variables when running task export. But it's not always clear, what type of filter is applied.

for example:
1) foreman-rake foreman_tasks:export_tasks TASK_SEARCH=all TASK_DAYS=3  -> 16 tasks
2) foreman-rake foreman_tasks:export_tasks TASK_SEARCH='' TASK_DAYS=3   -> 2822 tasks
3) foreman-rake foreman_tasks:export_tasks TASK_SEARCH=ALL TASK_DAYS=3  -> 16 tasks
4) foreman-rake foreman_tasks:export_tasks TASK_DAYS=3                  -> 2835 tasks
5) foreman-rake foreman_tasks:export_tasks                              -> 7396 tasks
6) foreman-rake foreman_tasks:export_tasks TASK_SEARCH=''               -> 32153 tasks



4. Why does the customer need this? (List the business requirements here)
To avoid confusion and mistakes

5. How would the customer like to achieve this? (List the functional requirements here)
Print the applied filter when running the command. Similar to cleanup-task 

     foreman-rake  foreman_tasks:cleanup NOOP=true VERBOSE=true AFTER=60d TASK_SEARCH=''
       ...
     [noop] deleting all tasks matching filter started_at < "2019-04-25 09:12:13" AND state = stopped


6. For each functional requirement listed, specify how Red Hat and the customer can test to confirm the requirement is successfully implemented.
When the command is executed, it should print the applied filter on stdout.


7. Is there already an existing RFE upstream or in Red Hat Bugzilla?
no


8. Does the customer have any specific timeline dependencies and which release would they like to target (i.e. RHEL5, RHEL6)?
asap


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


10. List any affected packages or components.
tfm-rubygem-foreman-tasks


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