Vitaliy Filippov b7e4d0c9bf Fix journal dirty_start position tracking and some debug prints 
Fixes two bugs found during HDD testing :-)

   `fio -bs=900k -iodepth=128` test with 16 MB journal
2) OSD stalled during `fio -bs=512k -iodepth=128` test with 64 MB journal

Vitaliy Filippov 161a23c966 Support reloading state when etcd says "revisions were compacted" 
Before this change, OSDs almost always died when one of the etcds was restarted,
even though the rest of them was still in quorum and the lease was still active

Vitaliy Filippov 2f999d8607 Reduce etcd memory usage 
With default --snapshot-count 100000 and GOGC=100 it easily reaches 6.6 GB
even when we only store 1-2 MB of data in it

Vitaliy Filippov a612cdca47 Release 0.9.3 
- Add patch for libvirt 9.0
- Add support for Proxmox VE 8.0
- Fix compatibility of the QEMU driver with iothread (QEMU rebuilds are coming)
- Fix vitastor-cli rm-data/rm/merge hanging when some OSDs are down.
  Allow deletions in unclean cluster at the cost of some data possibly
  "reappearing" when those OSDs start back. In that case you can just repeat
  the deletion request using rm-data.
- A bunch of bug fixes for snapshots:
  - Fix snapshot reads often not working at all with snapshot chain size > 2
  - Fix optimized snapshot data merge (children to parent)
  - Fix updating of image name index key during optimized merge
  - Fix auto-selection preventing the use of optimized merge with only 1 snapshot
  - Fix incorrect CAS retries during snapshot merge
  - Fix snapshot merge progress reporting
- Fix primary_read bitmap buffers use-after-free which could lead to
  incorrect allocation map reads
- Remove /usr/local/bin path from make-etcd
- Some documentation fixes
