Release 3.0.10

Important bug fixes (new store):
- Fix OSDs possibly refusing to start with "write metadata failed at offset xxx: Invalid argument"
  (fix buffer alignment during initial garbage collection)
- Rollback change from 3.0.4 - on-disk garbage entries are not skipped on start again. This change
  doesn't have any impact normally, but OSDs originally running 3.0.0-3.0.2 and then upgraded
  to 3.0.9 may hit a bug where 3.0.9 refuses to start due to entries marked as garbage too
  early and flushed to disk in 3.0.0-3.0.2.

Other changes:
- Auto-select the only RDMA device/port if there is only one
- Rollback one 3.0.9 change - there was no actual use-after-free :)
  (the problem was only relevant to an unstable development version)
- Fix `vitastor-nfs --trace` option
- Fix an unintended 1 second sleep in vitastor-cli rm-data
- Fix inode statistics not being cleared for a deleted pool
- Fix print to stdout in client
