Feature request: Add "docker task" subcommand

Hi all, I'm working on python-on-whales, which is a python wrapper for the docker CLI. I've had trouble manipulating/creating swarm tasks objects because there is no way to get information about them from the docker CLI.

It's also an issue we noticed in my company, when using the CLI to understand/debug a swarm cluster, we can't access many information about tasks (there is docker service ps, but only a limited amount of information about tasks is displayed).

I suggest adding 3 new cli commands which correspond to the 3 API endpoints in the docker daemon: https://docs.docker.com/engine/api/v1.40/#tag/Task

docker task ls
docker task inspect
docker task logs

I'm not a go programmer so I don't think I'll be able to contribute this feature though.

Thanks again for making docker so awesome :)

Start by reading the Docker Engine API v1.40 Task endpoints and the existing docker service ps behavior. Determine how docker task ls, docker task inspect, and docker task logs should map to those endpoints, including their expected output and options. Done means the three commands provide task information that the current CLI does not expose.
