Add Memory Target Trigger to Artifactory Charts using HPA

Starting from Artifactory version 7.111, for the Artifactory chart, HPA will function only when the replica count is a minimum of 2 (i.e., in High Availability mode). For the Artifactory HA chart, HPA will operate as expected.

Here's a sample configuration:

autoscaling:  
  enabled: true  
  minReplicas: 2   
  maxReplicas: 3  
  targetCPUUtilizationPercentage: 70  
  metrics: |  
    - type: Resource  
      resource:  
        name: memory  
        target:  
          type: Utilization  
          averageUtilization: 70 # Target memory usage is 70% of the allocated memory per pod
