Stack user can't be deleted

[Honza Pokorny]

When using "--teardown all", the stack user isn't properly deleted. The "userdel" command fails.

TASK [provision/teardown : Remove non-root user account] ***********************
task path: /root/tripleo-quickstart/roles/provision/teardown/tasks/main.yml:48
Friday 16 December 2016 12:55:36 -0500 (0:00:02.790) 0:00:22.469 *******
fatal: [dell-pe-fm120-1a.rhts.eng.bos.redhat.com]: FAILED! => {"changed": false, "failed": true, "msg": "userdel: user stack is currently used by process 8260\n", "name": "stack", "rc": 8}

The workaround is to run "userdel stack" twice manually before retrying.

This is latest master, using --release master.

Hello Honza,

I checked the relevant part of this role and it deals with stopping all the processes just before this. so to know what really happens I would need the full logs for the run that doesn't succeed, not just this failed task.

My suspicion is that the machine you're running on is slow and we only wait 5 seconds for the processes to exit. I'll increase this to 15 by waiting 3 seconds between each check.

    teardown: wait longer for processes to exit

    Increase the wait between retries from 1 to 3 seconds before the
    non_root_user gets deleted to avoid occasional errors.
