Allows for various environment variable overrides for use in AWS reference implementation
Overrides may use tpl functions to populate {{ .Release.Name }} in the values.yaml (needed for dynamic use between IBM & AWS implementations)
Partition.keycloak variables are not necessary for proper function of DDMS services so those variables are removed from configmap
Destination rules were added for AWS implementation - tested that this does not affect IBM
envVars: heading in devops/ibm/ibm-wellbore-domain-services-deploy/values.yaml was added so additional overrides can be done in the values.yaml of the deploy folder
