feat: Add HorizontalPodAutoscaler created and deletionTimestamp info into metrics

[IgorIgnatevBolt]

What this PR does / why we need it:

For some reason, there is no kube_horizontalpodautoscaler_created metric for HPA with creation timestamp information, PR is about to add it as a similarity to other objects.

Also, add kube_horizontalpodautoscaler_deletion_timestamp metrics to catch the deletion timestamp field.

How does this change affect the cardinality of KSM: (increases, decreases or does not change cardinality)

None
