Check all services by default on swarm mode

[mathcantin]

Why in the default mode, all containers are check by default and on the swarm mode we need to add labels by default?

That PR standardize the behavior between normal and swarm mode.

This was ARBITRARILY intentional with the thought process of "if they are using swarm, they should need to use labels". You disagree?

[mathcantin]

No, because there are actually no way to activate auto update for all existing and futur services, we need to add label on every services.

We could create a negative flag like "--no-labels", but that make options harder to understand. I think it's better to reuse existing options.

swarm == enterprise. if people arent readily putting labels on their services i feel like theres a bigger issue ya know?

[mathcantin]

Yes, it's true in production, but I think there are good use case in development or staging to enable on every services.

on the swarm mode we need to add labels by default?

I'm not aware of that. AFAIK you can use swarm without labels very well.

Meh. Ill put it for now. I dont see the issue. It was only removed as an opinion
