Log streaming does not work in proxy setups

Description

Log forwarding does not work in Proxy setups because the proxy environment variables were not set in the logging pods.

Solution

1. Set the http_proxy , https_proxy and no_proxy environment variables. Example:

   export http_proxy=http://<proxy>:3128
   export https_proxy=http://<proxy>:3128
   export no_proxy=<fqdn>,.<fqdn>,10.0.0.0/8,kerberossql.autosuitead.local,kerberospostgres.AUTOSUITEAD.LOCAL,rook-ceph-rgw-rook-ceph.rook-ceph.svc.cluster.local,localhost,127.0.0.1,kubernetes,kubernetes.default,kubernetes.default.svc,kubernetes.default.svc.cluster,kubernetes.default.svc.cluster.local,.svc,.svc.cluster,.svc.cluster.local,.svc.cluster.local.,.uipath.svc.cluster.local,argocd-repo-server,istiod.istio-system.svc,logging-operator-logging-fluentd.logging.svc.cluster.local,.local,.cluster,ai-helper-svc,ai-pkgmanager-svc,ai-deployer-svc,ai-appmanager-svc,ai-trainer-svc,studioweb-backend,studioweb-frontend,studioweb-typecache

2. Execute the following script which ingests the environment variables into the logging pods and restarts them.

   #!/bin/bash
   
   set -euo pipefail
   
   APP_NAME="logging"
   NAMESPACE="argocd"
   HTTP_PROXY="${http_proxy:-}"
   HTTPS_PROXY="${https_proxy:-}"
   NO_PROXY="${no_proxy:-}"
   
   # Create a temporary JSON patch
   PATCH_FILE=$(mktemp)
   
   cat > "$PATCH_FILE" <<EOF
