Add option for use hpa and pdb

I successfully tested remotely using the values:

replicaCount: 2

persistence:
  enabled: false

autoscaling:
  enabled: true
  minReplicas: 2
  maxReplicas: 5

pdb:
  enabled: true

resources:
  requests:
    cpu: 0.5
    memory: 1Gi

?

@santos-edu thanks for your PRs. I have not had a chance to test them or figure out why they're causing the test action to fail, but I'll try these out as soon as I can to determine if the issue is with your code updates or the action itself.

@0xThresh thanks for answer, in your time!
I tested with the same commands of the action, but I will try to find out here what happened...
