Add basic metrics to ImageCacheState and persist them, including allocated_bytes, cached_bytes, dirty_bytes, free_bytes and hit/miss info. Leverage periodic_stats() timer to call update_image_cache_state. In order to avoid outputting too much debug information, the original statistics output log level is changed to 5. Switch to json_spirit for encoding because encode_json encodes bool as "true"/"false" string. Remove rbd_persistent_cache_log_periodic_stats option because we need to always update cache state.
