[FEATURE REQUEST] poco logs follow flag

[petercseh-sf]

I would like to use poco logs to be able to follow the logs of all containers in a poco plan.
Right now poco logs <plan> prints the logs but only once and it won't follow.

Docker compose does this natively, when I type docker-compose logs -f . I would like to have the same functionality with poco.

Please if possible make it possible to add the flag anywhere after the "logs" command, for example:

• poco logs -f <plan>
• poco logs <plan> -f
• poco logs -f // use default plan

Output should be whatever docker-compose does.
