[bitnami/apache] Update templates to have conditionals for HPA

[amoon78]

Description of the change

• Add conditionals in deployment template to ignore replicas when autoscaling is enabled. (reference link)
• Swap spec.metrics.resource order in hpa template to avoid HPA controller reorders issue

Benefits

• For deployment template change, from kubernetes.io -

When an HPA is enabled, it is recommended that the value of spec.replicas of the Deployment and / or StatefulSet be removed from their manifest(s). If this isn't done, any time a change to that object is applied, for example via kubectl apply -f deployment.yaml, this will instruct Kubernetes to scale the current number of Pods to the value of the spec.replicas key. This may not be desired and could be troublesome when an HPA is active.

• For HPA template change, HPA controller won't try to reorder continuously

Possible drawbacks

Applicable issues

• fixes HPA is not working properly due to replicas set #29388
