Release 1.4.4

A couple of fixes for EC pools

- Fix a segfault possible on partial EC overwrite in 1234 -> 5030 rebalance scenario
- Fix two problems leading to EC pools stalling on rebalance & parallel sudden stops
  of OSDs, for example during a sudden poweroff of a host:
  - Recovery auto-tuning (1.4.0 feature) could apply too large delays and stall
    the EC journal - fixed by limiting delays with a new recovery_tune_sleep_cutoff_us
    parameter (10 seconds by default) and applying recovery pauses before write
    operations, not after them, to not occupy space in the journal for long time
  - Dynamic journal space reservation (1.3.0 feature) wasn't accounting new writes
    when checking the limit so OSDs could still fill the journal fully and stall -
    fixed by including new writes into the limit
- Print etcd dbSize instead of dbSizeInUse in status
