TT#15652 stime indexes for accounting.*_data tables

- required to support acc-cleanup's "backup" and "archive"
  modes. for "cleanup" mode, they are not needed considering
  the original plan with cdr delete triggers.

- delete triggers for accounting.cdr slow down the cleanup,
  so we take them out. separate cleanup jobs should be registered.
  this way, the performance of 3.x cleanup must be axactly restored.

- same for events; also there was no index for the
  events.timestamp column yet
