fix: camoproxy loadbalancer SLI
What
Update the camoproxy loadbalancer from a haproxy one to a GCP one.
This will add these metrics back:
Why
In gitlab-com/gl-infra/production#7181 (closed) we've migrated the camoproxy service to Kubernetes so haproxy is no longer used, and instead, we are using a google LoadBalancer created by the ingress.
The name of the loadbalancer is automatically generated and currently
has the name of
k8s2-um-8kvupfyn-camoproxy-camoproxy-6ygs428t
.
