ASRE-931: Add new variable shareProcessNamespace

[sho-equativ]

What

This PR introduces the shareProcessNamespace field in the PodSpec. When enabled, this feature allows all containers within a pod to share the same process namespace. This means containers can view and interact with each other's processes, enhancing communication and debugging capabilities between containers in the same pod.

How

• Added the shareProcessNamespace field to the PodSpec structure.
• Updated the pod creation logic to check for this field and configure the process namespace accordingly.
• Adjusted the container runtime settings to support shared process namespaces.
• Included tests to verify that containers can indeed share the process namespace when the field is enabled.
• Updated documentation to explain how to use shareProcessNamespace in PodSpec.

Can this PR be safely reverted and rolled back?

• [X ] YES 💚
• NO ❌
