Headlamp is not configured to use the istio helper for gateway and Netpol Selections.

Motivation

Big Bang now uses a helper to identify the gateway name to use for virtual services in packages. Headlamp does not follow this new convention. The package is also missing support for Istio Operator-less in the egress/ingress package Network Policies.

Acceptance Criteria

• Headlamp's default values template must be updated to use the getGatewayName helper to identify the correct istio gateway
• Headlamp package needs to have the Network Policies updated to support Operator-less deployments.
• Test Gateway and Nework policy changes with a Opeartor-ful and operatorl-less deployments.
