add a loop option for shell commands

[foadrezek]

I find myself running some shell commands multiple consecutive times, and thought of adding a loop mechanism, something like:
loop

1- Is there a way to leverage the shell_execute_cmd shell API? As the documentation specificies, this cannot be done from a shell context (i.e in the loop handler)
2- Is there a way to extract the handler of an shell command and call it directly ?
3- Use some shared memory/static variables for this purpose ? (i.e map the cmd name to the handler, later on the loop command can pick up this info and call the right handler)

Hi!
I think that's a great idea.

Is there a linux bash "watch" command equivalent in zephyr?
