Rename eth.beta to eth.prod fleet

[jakubgs]

Since we are nearing V1 it would make sense to rename our eth.beta fleet eth.prod.

I've checked this and it appears I cannot rename Google Cloud External IP addresses:

  # module.whisper.module.gc-us-central1-a.google_compute_address.host[7] must be replaced
-/+ resource "google_compute_address" "host" {
      ~ address            = "35.224.150.136" -> (known after apply)
        address_type       = "EXTERNAL"
      ~ creation_timestamp = "2018-09-08T19:37:58.877-07:00" -> (known after apply)
      ~ id                 = "russia-servers/us-central1/node-08-gc-us-central1-a-eth-beta" -> (known after apply)
      ~ name               = "node-08-gc-us-central1-a-eth-beta" -> "node-08-gc-us-central1-a-eth-prod" # forces replacement
      ~ network_tier       = "PREMIUM" -> (known after apply)
      ~ project            = "russia-servers" -> (known after apply)
      ~ region             = "us-central1" -> (known after apply)
      ~ self_link          = "https://www.googleapis.com/compute/v1/projects/russia-servers/regions/us-central1/addresses/node-08-gc-us-central1-a-eth-beta" -> (known after apply)
      + subnetwork         = (known after apply)
      ~ users              = [
          - "https://www.googleapis.com/compute/v1/projects/russia-servers/zones/us-central1-a/instances/node-08-gc-us-central1-a-eth-beta",
        ] -> (known after apply)

      - timeouts {}
    }

Which causes them to be re-created, which discards the reserved IP address.

I've checked the API and there is no mention of ability to rename a GC address: https://cloud.google.com/compute/docs/reference/rest/v1/addresses This Stack Overflow answer seems to confirm this: https://stackoverflow.com/questions/22687968/rename-reserved-ip-address-in-gce

The simplest solution would be to remove those addresses from the Terraform state and let them exist while we create new prod ones and use those. But according to the docs:

Only one resource at a time can use a static external IP address. https://cloud.google.com/compute/docs/ip-addresses/reserve-static-external-ip-address

[jakubgs]

So either I have to replace external IP addresses for Google Cloud instances in the eth.beta fleet when renaming it, or I have to write some kind of absolute dreadful hack into infra-tf-google-cloud Terraform module to let the hosts keep their wrongly named IP addresses.

after a brief discussion, we think breaking it is fine under the assumption that the client switches efficiently when it tries to hit a dead IP. Relevant work there:

• https://github.com/status-im/status-go/tree/develop/rtt
• https://github.com/status-im/status-react/issues/9394

I've checked the current stable Beta version and it also switches when a mailserver is dead, it just does it randomly instead of using any kind of ping, so this shouldn't disturb users much.

Changes are prepared in the rename-beta-to-prod branch. I'm going to wait until Adam deploys his new status-go changes to eth.beta so I can get the peer metrics for the fleet before proceeding: https://grafana.status.im/d/gxQG_R1Zk/status-peers

Instead of renaming I've created a new eth.prod fleet in: 9515e7c4

The old eth.beta fleet will be kept up for a few weeks after V1 is out to let users trickle out.
