The installer and ipactl used two different methods to determine
whether IPA was configured, unify them.
When uninstalling report any thing that looks suspicious and warn
that a re-install may fail. This includes any remaining 389-ds instances
and any state or files that remains after all the module uninstallers
are complete.
Add wrappers for removing files and directories to log failures.
