A registered FileSystemProvider that registers the "sftp://" scheme so that URLs with this protocol
are handled as remote SFTP Path-s - e.g., "sftp://user:password@host/remote/file/path"
An SFTP-aware DirectoryScanner that assumes all Path-s refer to SFTP remote ones and match patterns
use "/" as their separator with case sensitive matching by default (though the latter can be modified).
