Release 2.0.0

No breaking features, it's 2.0.0 just because it includes S3 and because
there are already too many 1.x releases :).

New features:

- S3 is finally available: https://vitastor.io/docs/installation/s3.html
- node.js addon is now packaged as a Debian package
- Support listing PGs by OSDs in `vitastor-cli ls-pgs`
- Implement offline TRIM support: [vitastor-disk trim](https://vitastor.io/docs/usage/disk.html#trim),
  [discard_on_start](https://vitastor.io/docs/config/osd.html#discard_on_start)
- Change used_for_fs pool option to used_for_app

Bug fixes:

- Fix several bugs in the node.js addon (a memory leak, an incorrectly triggered event loop)
- Fix a client crash (vitastor-cli rm) during deletion when writeback is enabled
- Fix PG object count statistics on deletion of non-existing objects
- Fix vitastor-nbd crash when mapping by ID instead of inode name
- Fix a client memory leak with enabled immediate_commit and write-back cache
- Add seccomp=unconfined for vitastor docker OSDs to not break io_uring
- Add udev and systemd to vitastor docker image
- Fix upgrading from pre-0.7.1 (very old) systemd units O_o
- Fix total object count calculation in rm_data
