#3062: overhauled statistics generation and cleanup
- switched to a single thread for database cleanup and statistics generation (executed sequentially)
- switched to preemptive deletion of items that are in status DeletionPending (for jobs: statelogs, taskdata, tasks)
- added code that aborts tasks whose jobs have already been marked for deletion
- added method UseTransactionAndSubmit in addition to UseTransaction in PersistenceManager
- updated DAO methods and introduced more bare metal sql
- introduced DAO methods for batch deletion
- fixed usage of enum values in DAO sql queries
- deleted unnecessary triggers tr_JobDeleteCascade and tr_TaskDeleteCascade in Prepare Hive Database.sql
- changed scheduling for less interference with janitor and other heartbeats
- increased scheduling patience from 20 to 70 seconds (to wait longer to get the mutex for scheduling)
- changed signature of ITaskScheduler.Schedule
- added base class for TaskSchedulers and moved assignment of tasks to slaves into it
- changed RoundRobinTaskScheduler to use bare metal sql
- made MessageContainer a storable type (leftover)
- updated HiveJanitorServiceInstaller.nsi
