Adding autoscaling to the CWL DAG and SBG end-to-end step-by-step DAG

[LucaCinquini]

Purpose

• This PR introduces autoscaling behaviour for 2 existing DAGs: the "cwl_dag" and the "sbg_L1_to_L2_e2e_cwl_step_by_step_dag"

Proposed Changes

• [CHANGE] Modify "cwl_dag" to use Karpenter for autoscaling
• [CHANGE] Modify "sbg_L1_to_L2_e2e_cwl_step_by_step_dag" to use Karpenter for autoscaling

Issues

• [New feature]: Concurrent Execution of N SBG end-to-end workflows #64

Testing

• After the changes, both the "cwl_dag" and the "sbg_L1_to_L2_e2e_cwl_step_by_step_dag" completed successfully (single execution only).

This looks good to me (although I don't have a ton of experience with Kubernetes and Karpenter). I also saw that it was successfully executed in issue #64.
