Description

  • Make the Thrasher class abstract by adding _do_thrash abstract function.
  • Change OSDThrasher, RBDMirrorThrasher, MonThrasher and MDSThrasher (maybe RSync too) to inherit from the template Thrasher and implement the abstract functions.
  • Check thrash_pool_snaps and create a new class for it.
  • Update the thrashers to follow the similar design - some has start/_run and some calls spawn.
  • rename thrashosds.py to osd_thrash.py
  • Move the OSDThrasher class from ceph_manager.py to osd_thrash.py
