* cache: improved cache cleanup on exit Ensure we do one full sweep before closing if cache has been modified. Before we would do periodic sweep every minute which would not kick in for very short snapshots, which Kopia does very frequently. This leads to build-up of metadata cache entries (q blobs) that never get cleaned until some long session. * caching: streamlined cache handling - deprecated caching-related flags, now cache is always on or off with no way to disable it per invocation. - reduced default list cache duration from 10min to 30s - moved blob-list cache to separate subdirectory - cleaned up cache info output to include blob-list cache parameters - removed ability to disable cache for per-context (this was only used in 'snapshot verify' codepath) - added ability to partially clear individual caches via CLI
