Create a platform task for setting SELinux booleans. Use an exception for the case when the booleans could not be set (since this is an error if not handled). Since ipaplatform should not depend on ipalib, create a new errors module in ipapython for SetseboolError. Handle uninstallation with the same task, which means the booleans are now restored with a single call to setsebool.
