[chore] add fargate cluster for testing installation

[jinja2]

Description:

• Adds github jobs to test install and upgrade for eks/fargate distribution with splunk-otel-collector helm chart.
• Adds minReadyTime (similar to minReadySeconds option in k8s)
• Removes unused expected_eks_values to simplify some test logic
• Updates to holderidentity for k8s leases (noticed same ids in install/upgrade test)

[jinja2]

The AKS install error seems legit with agent pod failing after sometime. Looking into this further.
