Subject: Impl ...

- launch.json: change debug cwd to the project root dir
- Add subcmd "mods"
- Docs
- Tidy up sample and debug config files
- Change core exec
  - 'dnf-list-instaled' -> 'rpm-list-installed' as dnf does not work
    on ro fs
  - Accept the exit code 1 from tar(allow live fs change)
- Add the generic sample config
- Fix 'run' subcmd not accepting empty task-id
- Change module loading: modules are not required to have
  the 'backup_backends' var
- Reduce required Python version by removing the use of match ... case
- Fix 'exec-append' not taking 'env' into account
- Remove use of exceptions from irrelevant packages
- Fix unimpl methods of NullBackupBackend
- Tidy up instantiation of raised exceptions
- Change "include" behaviour
  - Relative config paths are now resolved like #include C preprocessor
- Fix bug where "include" circular ref checked is not done with absolute
  paths of config files
- Add own exception hierachy
- aws-s3: change storage class only when "rot-storage-class" is
  different from "sink-storage-class"
