This patch adds a sysrestore module which allows ipa-server-install code to backup any system state so that it can be restored again with e.g. ipa-server-install --uninstall. The idea is that any files ipa-server-install modifies gets backed up to /var/cache/ipa/sysrestore/ while any "meta" state, like whether a service is enabled with chkconfig, is saved to /var/cache/ipa/sysrestore.state.
