Allow for Ingress APIs to have categories

When an api in the apidefinition has a name with tags like "myapi #demo #infra" it will result in categories in the Dashboard. When using the ingress and apidefenition

apiVersion: tyk.tyk.io/v1alpha1
kind: ApiDefinition
metadata:
  name: myapideftemplate
  labels:
    name: myapi
    template: "true"
spec:
  name: "myapi #demo #infra"
  ......

The name is ignored and and constructed via the function: https://github.com/TykTechnologies/tyk-operator/blob/39ff14bed1ed8b81f438821d9af443eb18985ec8/controllers/ingress_controller.go#L279

func (r *IngressReconciler) buildAPIName(nameSpace, name, hash string) string {
	return fmt.Sprintf("%s-%s-%s", nameSpace, name, hash)
}

This will not allow for having categories on you ingress api's. I would like to propose to change the code to:

name := r.buildAPIName(ns, desired.Name, template.Spec.Name, hash)

func buildAPIName(nameSpace, ingress_name, template_name, hash string) string {
	r, _ := regexp.Compile("#\\w+")
	categories := r.FindAllString(template_name, -1)
	return fmt.Sprintf("%s-%s-%s %s", nameSpace, ingress_name, hash, strings.Join(categories, " "))
}
