[docker service ls] should recognize and format published port ranges

[jefflill]

I have some services that publish lots of ports in a range to the Docker ingress network (this is a reverse proxy). The docker service ls command does not recognize the port range and instead outputs the individual port mappings which looks pretty ugly.

It would be really nice if the CLI could recognize a range and output a syntax like: *:5300-5499->5300-5499

In the example below, the neon-proxy-private service published ports 5300-5499 and the neon-proxy-public service published 5100-5299. You can see the long list of individual ports by scrolling to the right.

At the very least we should truncate the output and add a --no-trunc like other list commands.
