#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
