Release 1.4.5

- Fix a write stall caused by incorrect journal trimming introduced in 1.4.4 :)
- Fix PGs sometimes hanging in "starting" state on mass OSD restarts
- Fix a rare crash with "map::at" during OSD pings
- Use new defaults for non-capacitor (desktop) SSDs - improves T1Q256 random write from ~6k iops to ~45k iops
- Make journal_trim_interval configurable
