Support --default-load-balancer-scheme flag in helm chart

[andremarianiello]

Describe the feature you are requesting
Support --default-load-balancer-scheme flag in helm chart. Many of the controller flags are exposed as helm chart values, but not this one.

Motivation
I want to change the default load balancer scheme to internet-facing so that some services that I cannot set annotations on are automatically made internet facing.

Describe the proposed solution you'd like
Expose the --default-load-balancer-scheme as a helm chart value

Describe alternatives you've considered
The service I want to be internet-facing is created by a controller, and the controller does not have the ability to add custom annotations to the service. I also don't want to install a whole mutating webhook solution just to add the annotation when the controller itself already supports changing the default scheme. Additionally, I don't see a way to set this flag via environment variable.

That's a good idea, you're welcome to contribute a PR for the feature and we'll take a look once it's made. It should be a fairly simple change.
