Why: * Protected variables were introduced to support temporary accounts so that temporary users could be filtered based on their IP address. * Filters that use protected variables are protected in order to preserve privacy. This can't be undone. * It is mistakenly possible to protect a filter that does not use protected variables (T378553). We need a mechanism to fix these mistakes. What: * Introduce a maintenance script that takes a filter ID and, if the filter is protected, sets it to unprotected while maintaining any other existing privacy levels. Bug: T378551 Change-Id: I4dfe3970221397d5be5ea0697490d8c8e3726adf
