[venkateshjayagopal]

Adding new env variable for controller, CTRL_SEARCH_REGISTRIES

Tested with single and multiple URL. Note: When using multiple URLs we need to use backslash "\" to escape ",".

Example,

root@Host-01-RKE2:/home/neuvector/helm_master/neuvector-helm/charts/core# helm install neuvector -n neuvector --set tag=jenkins-nv-build-fleet-5296,controller.image.repository=nvpublic/co,enforcer.image.repository=nvpublic/en,manager.image.repository=nvpublic/ma,controller.apisvc.type=NodePort --set manager.image.hash=sha256:4e2b70e991e8fad42009378c2fac7a2415b8c164efbe75d73f1addef66d379d8 --set controller.federation.managedsvc.type=NodePort,controller.apisvc.type=NodePort --set 'controller.certupgrader.env[0].name=EXPIRY_CERT_THRESHOLD,controller.certupgrader.env[0].value=3816h' --set "controller.certupgrader.schedule=10 * * * *,internal.autoRotateCert=true" --set "controller.search_registries=https://recovery.quay.io/\,https://aws.repository.com/" ./
