Maintenance: support for automatic GC Moved maintenance algorithms from 'cli' to 'repo/maintenance' package Added support for CLI commands: kopia gc - performs quick maintenance kopia gc --full- perform full maintenance Full maintenance performs snapshot gc, but it's not safe to do this automatically possibly in parallel to snapshots being taken. This will be addressed ~0.7 timeframe.
