Allow recreation of specific named volumes

When Docker Compose detects a named volume definition change, deployment can fail with:

Volume "<name>" exists but doesn't match configuration in compose file. Recreate (data will be lost)?

To opt in to automatic recreation for volumes that are safe to recreate (for example tmpfs-backed volumes),
set the top-level volume label cd.doco.volume.recreate: "true".

Only volumes with this label are eligible. Unlabeled volumes are never removed automatically.

volumes:
  socket:
    name: beszel-agent_socket
    driver: local
    driver_opts:
      type: tmpfs
      device: tmpfs
      o: size=1k,uid=65530,gid=0,mode=0700,noexec
    labels:
      cd.doco.volume.recreate: "true"
