Release 0.9.4

- Improve QEMU driver performance by integrating io_uring in it (up to 1.5x total iops improvement)
- Fix QEMU driver deadlocks which started to reproduce in qemu-img after iothread fixes
- Fix `vitastor-cli status` reporting more etcds than actually exists (fix etcd address duplication in config on reload)
- Fix `vitastor-cli ls` crashing on inodes in non-existing pools
- Delete old garbage /pool/stats/ keys for non-existing (deleted) pools
- Reduce memory usage of etcds initialized by make-etcd script
- Fix OSDs almost always crashing on etcd restart due to "revisions were compacted" (support reloading state from etcd)
- Fix a crash and a stall possible mostly in HDD setups with small journal and big (512k, 900k) random writes
- Add notes about HDDs to documentation. You are officially allowed to use HDD-only Vitastor with HGST/Toshiba/EXOS :)
