[GC] Basic garbage collection for build host images and containers

• Experimental feature: automatical host cleaning GC procedure will be activated only when WERF_ENABLE_HOST_STORAGE_GC=1 is set.
• Werf may perform GC procedure in main commands (werf-build, werf-converge, etc.).
• To manually call GC procedure use werf host cleanup command.
• Algorithm and options:
  • Werf will try to maintain 80% disk usage by default and perform deletion of old images build by werf (and containers, and dangligh images as well). User may specify different threshold percentage with --allowed-volume-usage=N (WERF_ALLOWED_VOLUME_USAGE) option.
  • Werf tries to detect docker storage volume to check volume usage. User may specify --docker-server-storage-path (WERF_DOCKER_SERVER_STORAGE_PATH) option manually to specify volume where docker storage directory reside.
