Provisioning only appends systems to xyz.out

[mglantz]

Describe the bug
Provisioning playbooks only append new things to xyz.out files. When doing repeated deployments this causes things to fail. GitLab deployment for example, I suppose it will also mess up more things such as providing duplicate info to students.

To Reproduce

1. Provisioning environment two times.
2. Check xyz.out files
3. Find duplicate information

Expected behavior
We should create xyz.out files anew when provisioning, not appending information.

Workaround: Clean out xyz.out files before provisioning again..

@pgustafs says that this is a feature. How to manage it then when you re-provision?

Create a random string on the filename or add a timestamp?
