Clean up more files and directories created by the installer(s)
    
    Ideally all files created during an IPA server installation are
    removed by the uninstaller. Some files are purposefully left,
    like token passwords, private keys, logs and more. Add an
    allow list for those files.
    
    Include a test to catch any additional files that may be created
    and left behind.
