Dev 22129 definable ingress class ingress.tpl

[bradsoper]

Some customers have multiple ingressClasses. They need a way to define the ingressClassName for the ingress objects. This PR will add the ability to define the ingressClass. If no ingressClassName is defined it will take the default ingressClass. This will also fix the issue we have with the ingress objects being hardcoded to the ingressClassName 'nginx'

Here is the dev ticket: https://cnvrgio.atlassian.net/browse/DEV-22129

@bradsoper this is a feature request that’s require changes across the stack. Operator, RoR web app, and more. I would suggest to open a issue and discuss it mainly with product.

Understood, I see now we do define the ingressClassName in the app as well. I will discuss with product. Thank you
