Release 1.2.0

New features:

- Implement CSI volume expansion
- Implement CSI volume snapshots
- CSI driver now requires Kubernetes >= 1.20

Bug fixes:

- Important bug fix for EC: fix EC n+k, k>=2 read recovery in ISA-L version returning
  incorrect data when reading at least the second chunk out of multiple missing chunks
  without reading the first one. All users of EC n+k, k>=2 should upgrade as soon as
  possible, and upgrade should be conducted with downtime: first stop all clients
  (VMs/containers), then all OSDs, then upgrade and restart everything.
- Fix unstable statistics aggregation in monitor (affecting vitastor-cli status and df)
- Make udev not wait for OSDs to start during boot
- Do not report negative numbers of offline PGs in vitastor-cli status when changing PG count
- Report both old and new PG counts in vitastor-cli df when changing it
- Fix OSDs sometimes not starting with "The code only supports journal versions 1 and 2,
  but it is 2 on disk" error after upgrading from pre-1.0 versions and letting OSDs run
  for some time
- Fix monitors sometimes returning old PG count back after OSD configuration changes
- Make monitor PG changes more stable and timeout errors less probable
