[feature] Add "--bind" argument to "sonar list"

[mct]

What does this PR do?

Adds sonar list --bind argument, to easily display the IP address a port is bound to.

Searches the list of display columns for the word port and inserts the word bind immediately after it. This lets it work nicely when only --bind is passed, or when called with --stats --bind, or even with --columns port,name --bind

How was this tested?

Tested on Linux and macOS with:

sonar list
sonar list --bind
sonar list --bind --stats
sonar list --columns port --bind
sonar list --columns pid,port --bind
sonar list --columns port,pid --bind
sonar list --columns port,name --bind
sonar list --columns pid --bind # bind address not displayed, because "port" not shown
sonar list --columns pid,process,type --bind # bind address not displayed, because "port" not shown

Checklist

• I have tested this on my platform (macOS / Linux)
• My changes don't break existing functionality
• I have updated documentation if needed

Hi @mct,
You are aware that it's possible to show the up a port is bound to with the columns flag?

sonar list -c port,process,pid,type,url,bind
PORT   PROCESS                      PID     TYPE     URL                     BIND   
1780   proxy (traefik:3.0)          35029   docker   http://localhost:1780   0.0.0.0

I'm not against making it easier to add columns on top of the default ones, but then i think we should generalize this. If you think it's a very relevant flag to add and will make the tool more useful for you then i'm not against adding it.

And thanks a ton for your contribution, much appreciated!!

It's certainly possible without this feature to display the bound IP using sonar list -c port,bind,process,container,image,cport,url, but that's somewhat impractical to type each time :-) And because list is a second-level command under sonar, it's difficult to e.g. create a bash alias for it, the way one can with, say, alias ls="ls -AF"

Perhaps this could be generalized by having sonar look for an environment variable SONAR_LIST_COLUMNS to contain the default list of columns, if -c is not specified?
