Usage:
  NAMESPACE=<ns> [HF_TOKEN=<token>] deploy/utils/setup_benchmarking_resources.sh

Sets up benchmarking and profiling resources in an existing Dynamo namespace:
  - Applies common manifests (ServiceAccount, Role, RoleBinding, PVC)
  - Creates HuggingFace token secret if HF_TOKEN provided
  - Installs benchmark dependencies if requirements.txt exists

Prerequisites:
  - Dynamo Cloud platform must already be installed in the namespace
  - kubectl must be configured and pointing to the target cluster

Environment variables:
  NAMESPACE         Target Kubernetes namespace (default: default)
  HF_TOKEN          Hugging Face token; if set, a secret named hf-token-secret is created (optional)
