Release 1.6.0

New features:

- Implement "hierarchical failure domains" and other complex distribution rules, for example
  EC 4+2 over 3 DC, with 2 chunks per each DC ([documentation](docs/config/pool.en.md#level_placement))
- Make OSDs handle ENOSPC - now cluster stays online even if some OSDs fill up
  to 100 %, only writes requiring free space hang
- Implement Stage/Unstage & volume locking for CSI to prevent parallel mounting
  and/or modifications of the same volume
- Warn about full and almost full OSDs in vitastor-cli status
- Add an experimental NBD netlink map mode as an option ([documentation](docs/usage/nbd.en.md))
- Add --pg parameter to vitastor-cli describe, print objects with 0x in human-readable format too
- Add [administration docs](docs/usage/admin.en.md)

Bug fixes:

- Fix client operation retry timeout - previously the timeout wasn't applied and writes were
  retries almost instantly
- Fix monitors crashing on invalid pool configurations
- Fix journaling - make each journal write wait for all previous journal writes
- Fix monitor thinking that OSD weight is 0 after deleting /osd/config/ key online
- Fix a write stall caused by flusher possibly not trimming journal on rollback
- Set 32k csum_block_size for HDD by default in vitastor-disk
