Add Option to Set Proxy Service as ClusterIP Type in KOTS Admin UI

[jimmybrancaccio]

Is your feature request related to a problem? Please describe

For users who don't use the Proxy service as a LoadBalancer and instead have their own LoadBalancer in place, it would be very helpful to have the ability to set the Proxy service as ClusterIP instead. I believe having to manually set this has caused several failed Gitpod updates for me.

Describe the behaviour you'd like

Ideally a simple toggle in the admin UI would be excellent.

Describe alternatives you've considered

Manually editing the service for the moment (kubectl edit svc proxy -n gitpod).

Additional context

This would in fact be a very worthy improvement to make. An immediate solution for this could be as follows:

• We add a field to our experimental configuration to set proxyServiceType, by default being LoadBalancer
• From KOTS UI, this can be provided as a patch in the additional configuration section.
• We will document this as a potential work-around, and that it is experimental/might change in the future.

Same problem here, would be very nice to have

Same issue. That would be really useful.
As far as I can tell, any changes/redeployment also reverts it back to Loadbalancer type and leaves "readiness-check-pod" in CrashLoopBackOff.

@nandajavarma confirming #10537 has worked as expected for me. Thanks!
