feat(chart): add service.yaml

[sanadhis]

What problem:
I need to install caddy to K8s, but I don't need external load balancer.

Why this is a solution:
By adding this loadBalancer.enabled value, which default to true, we can make the load balancer optional. This is also to ensure smart transition to service.yaml for already-existing user of this helm chart.

@sanadhis thanks for your contribution!

May I ask to include the new keys in the values.schema.json file?

@sanadhis internalTrafficPolicy and externalTrafficPolicy have different behaviour (internal for traffic routing exteral for preserving client IP) I'm not sure about the last changes you included, can you give us some context? 🤔

Thanks!

Hey, yes I am well aware, I was thinking to keep things simple. Sure I can add it back. I'll do some refactor also since we provide default value anyway. I am also squashing my commits

@mavimo can we merge this one please? Thanks!

[mavimo]

@sanadhis I'll try to run the validation and merge ASAP

I'm planning to release a new version as soon as this is merged.

Hi @mavimo can we merge this please? I have seen few releases have happened since.

Otherwise if you're not convinced with the change we can close it. Though I would say I would prefer not to create my own fork.

Thanks @mavimo !!
