RAHUL KHIYANI 4999508454 prometheus-process-exporter: Add pod/container security context
This updates the prometheus-process-exporter chart to include the pod
security context on the pod template. This changes the pod's
user from root to the nobody user instead

This also adds the container security context to set
allowPrivilegeEscalation to false and readOnlyRootFilesystem to true
