Add HTTPRoute support to minecraft chart

[toddejohnson]

I've moved from ingress to gateway and as part of that now use httproute more. This attempts to add HTTPRoute support to the extraports.

Todo:

• Bump chart version
• Add example to values.yaml
• Validate values.schema.json with new items

Thanks. Yeah, adding to the values schema would be great.

In general, I'm wondering when you're needing http for the Minecraft server? For map exposure mods/plugins?

Doesn't look like Ingress is added but will take a try tonight.

Map is what I'm using it for today as I haven't had time to do something more intelligent. Throw resources at it instead of being elegant.
