[Cadence] Support all service publishing types with the frontend service

[pregnor]

Is your feature request related to a problem? Please describe.

Currently the Cadence frontend service only supports the service publishing types clusterIP, nodePort, loadBalancer (with ephemeral IP).

Describe the solution you'd like to see

Add support for loadBalancer (loadBalancerIP), externalName, ingress service publishing types to support more use cases.

Describe alternatives you've considered

Additional context

I don't quite follow, isn't it supported here?

banzai-charts/cadence/templates/server-service.yaml

Line 14 in d8d883e

type: {{ .Values.server.frontend.service.type }}

Because I've used this helmchart to deploy frontend with LoadBalancer and it works fine.

[pregnor]

You are right, it does support loadBalancer configuration with ephemeral IPs.
loadBalancerIP configuration option may be considered in the future.

Edit: edited the description accordingly.

---

FTR externalName configuration is required to support externalName service publishing and the support for ingress configuration has to be investigated.
