feat: add verify-feature retention subcommand with comprehensive testing and validation Add a `verify-feature retention` subcommand that allows users to preview and validate retention policy changes without running the actual Zot server. The command runs GC and retention tasks in dry-run mode for immediate feedback. - Run verify-feature retention standalone without starting the server - Preview retention policy decisions in dry-run mode - Configurable GC interval override via command-line flag - Optional timeout for task completion - Configurable log output (stdout or file) Basic usage: ```bash zot verify-feature retention <config-file> ``` With log file output: ```bash zot verify-feature retention -l /var/log/zot-retention-check.log <config-file> ``` With GC interval override (runs GC tasks every 30 seconds): ```bash zot verify-feature retention -i 30s <config-file> ``` With timeout (wait up to 5 minutes for tasks to complete): ```bash zot verify-feature retention -t 5m <config-file> ``` Combined flags: ```bash zot verify-feature retention -l /var/log/zot-retention-check.log -i 1m -t 10m <config-file> ``` The command supports overriding GC settings from the config: - `-i, --gc-interval`: Override the GC interval setting (applies to all storage paths including subpaths) - Refactored `RunGCTasks` from `controller.go` to be reusable - Added `checkServerRunning` validation to prevent conflicts - Implemented signal handling for graceful shutdown - Added configuration sanitization and logging - Set GCMaxSchedulerDelay programmatically (not user-configurable) Added tests for coverage on main function: - Negative test cases (no args, bad config, GC disabled, server running) - Both BoltDB and Redis - Retention enabled scenarios with complex image setups - Retention disabled scenarios - Delete referrers functionality - Subpaths configuration - GC interval override validation Run the verify-feature retention tests: ```bash go test -v ./pkg/cli/server -run TestRetentionCheck ``` Signed-off-by: Andrei Aaron <andreifdaaron@gmail.com>
