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 wiring, dropping related vars/outputs/firewalls and adding logs port defaults in the Nomad module.

• Infra removal (logs collector):
  • Delete google_compute_global_address.orch_logs_ip, module.gce_lb_http_logs, logs collector firewall rule, and google_compute_security_policy.disable-bots-log-collector in nomad-cluster/network.
  • Remove DNS/output for logs IP (network/outputs.tf) and nomad-cluster/outputs.tf exposure.
  • Drop logs_proxy_port/logs_health_proxy_port variables from nomad-cluster/network/variables.tf and nomad-cluster/variables.tf.
  • Remove named_port entries for logs from nomad-cluster/nodepool-client.tf.
• Wiring changes:
  • Stop passing logs_proxy_port and logs_health_proxy_port through provider-gcp/main.tf into nomad-cluster and nomad.
• Defaults:
  • Add defaults for logs_proxy_port and logs_health_proxy_port in iac/provider-gcp/nomad/variables.tf.
• Minor:
  • Preserve nomad_port in nomad-cluster/main.tf (re-added line).

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.
