ADHOC fix (cleaup): auto-cleanup by default

enable auto-cleanup by default, to cover the conern highlighted on code-review:

    Looks good. But would clean up by default. I am not aware of any project
    that needs to keep the old copies. So I vote for setting to something that
    makes sense. Instead of using this role and then need to apply this config
    to get a behavior that should be the default.

Author accept the concern and applies corresponding change
