CDB-2757 Implemented sync now functionality along the way (@see ticket CDB-1100)
CDB-2757 Added superadmin endpoint for listing all users synchronizations
CDB-2757 Sync filter
Merge branch 'master' into CDB-2757
CDB-2757 Finally found the issue with sync tables (error while moving from cdb_importer to public schemas caused data to not get updated), plus written a rake task to not need to rely on a daemon running ruby code (will use cron instead)
CDB-2757 Added rake option to trigger all syncs no matter if they should run or not
Merge remote-tracking branch 'origin/master' into CDB-2757
