Release 0.8.9

- The tests are now stable and run in a CI system based on Gitea CI
- The release includes final bug fixes for EC:
  - Implement missing EC recovery of allocation bitmap when built with ISA-L
  - Fix broken snapshot export with EC (allocation bitmap reads were giving incorrect results previously)
- Also fixed bugs manifesting under heavy load:
  - Fix monitor possibly applying incorrect PG history on retries
  - Fix monitor incorrectly changing PG count when last_clean_pgs contains less PGs than the new number
  - Allow writes to wait for free space again, but now correctly (previously dropped in 0.8.2)
  - Fix a rare segfault in client (handle client stop during incoming stream handling in 1 more place)
  - Make monitor correctly handle etcd connection errors - it could die instead of connecting to another etcd
  - Fix OSD rarely being unable to report PG states after a PG was taken over by another OSD
- Fixed return code for incomplete EC objects (now EIO) and made cluster client retry this error
- Made other small changes for tests: timeouts, nice/ionice for etcd, waiting conditions, NBD device checks and so on
