Add className to ExposeDeploymentViaIngressOptions

[chneau]

Description of the feature or enhancement:

Being able to set className on deployment.exposeViaIngress("/")

Use Case:

Consistency between a constructor and an "exposeXXX".
Make code shorter to write and more meaningful by deleting boilerplate and repetitive code.

Proposed Solution:

deployment.exposeViaIngress("/",{ className: "nginx" })

Other:

How I fix at the moment:

	const service = deployment.exposeViaService();
	const ingress = new Ingress(chart, "ingress", { className: "nginx" });
	ingress.addRules({
		backend: IngressBackend.fromService(service),
		host: host,
		path: "/",
	});
