Release 0.6.14

- Fix IPv6 address parsing
- Fix "cannot read bytes of undefined" in the monitor on a fresh DB
- Fix possible hangs of read requests on OSD restarts without immediate_commit=all mode
- Fix OSDs skipping misplaced recovery in some cases
- Fix OSDs possibly dying with "map::at" errors when other OSDs are stopped
- Fix division by zero in ls if all pool OSDs are down
