Release 0.5.7

- Fix multiple bugs leading to OSDs sometimes being unable to correctly activate PGs
  when a lot of PG peering events occurred in a small amount of time
- Fix a bug where OSDs could list incomplete object versions during peering. The bug
  manifested with "local rollback operation failed" messages in OSD logs
- Fix a bug where misplaced chunks for degraded and incomplete objects were not removed
  from extra OSDs during recovery
- Fix incorrect PG history configuration resulting in OSDs being unable to find some
  of the objects after a PG count change
- Simplify block layer write ordering logic
- Avoid extra data move when a lot of OSDs are first stopped for long time and then restarted
- Fix incorrect degraded & misplaced object statistics after a completed rebalance
- Fix incorrect usage of pg_minsize instead of the minimal possible object chunk count in EC pools
