Improve poor FreeIPA scaling

[ElliottKasoar]

Creating and deleting FreeIPA users scales very poorly, which appears to be significantly affected by the output steps. For example:

With current output:

• Creating 5 users: 8s
• Creating 50 users: 252s
• Deleting 5 users: 6s
• Deleting 50 users: 101s

With no output:

• Creating 5 users: 6s
• Creating 50 users: 97s
• Deleting 5 users: 5s
• Deleting 50 users: 43s

Just to add some info, it appears its the loops in the workflow that adds a lot of the time (see https://github.com/StackStorm/st2/issues/4882).

This issue is not directly tied to the output, as similar issues occur with the output removed once 100+ users are being created or deleted - the creation/deletion itself on FreeIPA is occurs relatively quickly, but the action is very slow to finish.

Calling a single script once, which loops over the users (e.g. https://github.com/stfc/ansible-jupyter/tree/main/scripts) appears to be far more efficient. Subbing these scripts in for the built-in action may be the best approach.

Closed as wont fix, as we've switched to a script
