Add wstunnel debug level and external template support

[dciangot]

Introduces new configuration options for wstunnel:

1. Debug Level Control:

   • Added wstunnelDebugLevel flag in values.yaml (default: "DEBUG")
   • Supports standard log levels: DEBUG, INFO, WARN, ERROR
   • Updated wstunnel-template_nginx.yaml and wstunnel-template_traefik.yaml to use variable
   • Config passed through InterLinkConfig.yaml to wstunnel templates

2. External Template Reference:

   • Added externalTemplate flag to reference local files or ConfigMap names
   • Added useExternalConfigMap flag to use existing ConfigMap instead of creating one
   • Priority: externalTemplate > customTemplate > templateType > default

Usage examples:

• Set debug level: virtualNode.network.wstunnelDebugLevel: "INFO"
• Use local file: virtualNode.network.externalTemplate: "my-custom-template.yaml"
• Use ConfigMap: virtualNode.network.externalTemplate: "my-configmap" and useExternalConfigMap: true
