Subject: [PATCH] test: adding support for monitoring in dev-create-cluster
 script

Adding a new '-m' option for activating monitoring during
cluster setup. With this option turned on, the script will handle the
installation of the monitoring stack and configure the dashboard to
connect to the newly installed Prometheus server automatically.
