[feature parity \w docker-compose] Support !reset and !override tags

[theCalcaholic]

Is your feature request related to a problem? Please describe.
podman-compose supports compose file merging, but gives no possibility to reset/delete sequence type values from the base yaml file. For example, assuming a merge with the command podman-compose -f base.yaml -f override.yaml it's impossible to remove a port configuration that has been defined on a service in base.yaml since any new definitions in override.yaml will be merged with the existing list.

Describe the solution you'd like
docker-compose offers yaml tags to deal with this situation: !override allows replacing the base configuration, while !reset allows removing the base configuration in the override config, e.g.:

# base.yaml
services:
  my-service:
    image: some/image:latest
    ports:
      - 8080:80
      - 443:443

# override.yaml
services:
  my-service:
    ports: !reset []

# override.yaml
services:
  my-service:
    ports: !override
      - 80:80
