feat: Add estimated instance warmup and ability to use deprecated marketplace images for ASG, change default PAN-OS versions to 10.2.9-h1

[sebastianczech]

Description

PR delivers changes:

• in ASG module:
  • introduce new variable include_deprecated_ami, which adds ability to use deprecated marketplace images
  • introduce new variable scaling_estimated_instance_warmup used to define time time until a newly launched instance can contribute to the CloudWatch metric
  • update default VM-Series image to 10.2.9-h1 (because of CVE-2024-3400)
• in VM-Series module:
  • update default VM-Series image to 10.2.9-h1 (because of CVE-2024-3400)
• in examples:
  • extend 3 autoscaling examples about variable scaling_estimated_instance_warmup
  • use VM-Series image 10.2.9-h1 (because of CVE-2024-3400)

Motivation and Context

Initially PR was raised because of #35, but while testing changes there were noticed problems with deprecated VM-Series images, so in order to fully test changes there were required improvements in other modules and examples.

How Has This Been Tested?

Code was tested locally in the lab and via ChatOps.
