Elasticsearch: Add security context for exporter pod/container

Browse Source 
This adds the security context snippet for the elasticsearch
prometheus exporter pod. This changes the pod's user from root to
the nobody user instead

This also adds the container security context to explicitly set
allowPrivilegeEscalation to false
