Adding support for `service: loadBalancer` for Unifi chart

[mddeff]

Hey, would there be any objection to merging in a change that allows for support for service of type LoadBalancer for the Ubiquity Unifi controller chart? Being able to expose all of the endpoints can be useful in several environments.

Example change. Any PR would include everything variable-ized and bubbled up to the main chart values.yaml.

Thoughts?

Have a look at PR and let me know if that works for you?

@duhow Sorry for the delay at looking at this, thank you for putting that together! I'll take it for a spin this week and make sure it works as expected but it looks like on the surface it should do the trick.
