Release 0.8.6

Important fixes:

- Fix possibly incorrect EC parity chunk updates with EC n+k, k > 1 and when
  the first parity chunk is missing

Minor fixes and improvements:

- Fix incorrect EC free space statistics in vitastor-cli df output
- Speedup vitastor-cli startup in clusters with RDMA
- Remove unused PG "peered" state (previously used to update PG epoch)
- Use sfdisk with just --json in vitastor-disk (--dump --json isn't needed)
- Allow trailing comma in sfdisk output (fixes sfdisk 2.36 compatibility)
- Slightly improve RDMA send/receive code
- Reduce RDMA memory consumption by default (rdma_max_recv/send = 16/8)
- Use vitastor-cli instead of direct etcd interaction in the CSI driver
