Remove load balancer infra for logs collector

[sitole]

When 6662158 is deployed, we no longer need an infrastructure provisioning load balancer for the logs collector.

---

Note

Removes the external logs collector load balancer and related IP, DNS, firewall, outputs, and variables; sets logs port defaults in the Nomad module.

• Infrastructure (GCP):
  • Remove external logs collector load balancer: delete google_compute_global_address.orch_logs_ip, module.gce_lb_http_logs, related firewall logs_collector_firewall_ingress, and network/outputs.tf logs_proxy_ip.
  • Drop logs collector DNS/output wiring in nomad-cluster/network and nomad-cluster/outputs.tf.
  • Remove client named_port entries for logs and logs-health in nodepool-client.tf.
• Modules/Wiring:
  • Stop passing logs_proxy_port and logs_health_proxy_port through provider-gcp/main.tf -> nomad-cluster.
  • Remove logs_proxy_port and logs_health_proxy_port variables from nomad-cluster/network/variables.tf and nomad-cluster/variables.tf.
  • Remove logs_proxy_ip outputs from nomad-cluster and nomad-cluster/network.
• Variables:
  • Remove root-level logs_proxy_port and logs_health_proxy_port variables in provider-gcp/variables.tf.
  • Add defaults for logs_proxy_port and logs_health_proxy_port in nomad/variables.tf.

Requests are still coming to the load balancer even after the rollout.

Resolved in person. I think we can now move forward once we understand why this is happening.
