RFE: switch to override %config file behavior

[pmatilai]

For all the disabler switches in rpm, there's no way to disable %config file special handling. Various use-cases include, but probably not limited to:

• reinstall package to clean state
• when uninstalling something, you often want the configs gone too

• when uninstalling something, you often want the configs gone too

Having something along the lines of a "purge" mode would make some sense. It would be very appealing for mass system management purposes to be able to do that.

Yup, that's exactly the use-case I was referring to.
