Image Cleaner Plugin Crashes due to OOMKill

[tshaiman]

Describe the bug

• when image cleaner runs on our cluster it crashes due to OOMKill
• since this is a plugin, we cannot control its resource allocation

To Reproduce
Steps to reproduce the behavior:

1. enable the plugin on large AKS Cluster ( few hundrerd Pods)
2. wait for OOMLill
3. investigate the Resource allocation : the pod has max of 100Mi RAM ,which for large clusters is insufficient

Expected behavior

• consider release this component as Helm chart so customers can choose their own Mem allocations
• increase Mem allocation on the plugin to at least 250Mi

Screenshots

Environment (please complete the following information):

• Kubernetes version : 1.25.5
