VM testnet tx-nodes & blockscout

[tkporter]

Description

Very chunky PR, here's a rundown of what's included which will make review easier:

• new optional env var for .env files: VM_BASED
• tx-nodes now also spun up with Terraform
• tx-node internal TCP load balancer spun up with Terraform (this is so blockscout on the same VPC network in a kubernetes cluster can talk to the tx-nodes)
• blockscout working with VM tx-nodes-- blockscout uses the internal IP address of the tx-node internal TCP LB to do all of its RPCs
• VM testnets have their own VPC networks unless the .env file specifies KUBERNETES_CLUSTER_NAME as celo-networks-dev. This is so ethstats/blockscout that is on the kube cluster celo-networks-dev will be on the same VPC as the VM testnet
• Refactor of celotool env-related utils out of utils.ts and into env-utils. This is what's to blame for the vast majority of file changes. Unfortunately this was necessary because otherwise I was running into circular import issues :(
• In order to make sure we don't try to create/destroy the default VPC network with Terraform, I separated out a module for creating/destroying a network. Celotool makes sure this is not done for the default network. Terraform won't allow a network to be destroyed if it's being used by something, but it causes terraform commands to fail, so this was necessary. See packages/terraform-modules/testnet-network/README.md for more deets

Sorry for jamming all this into 1 PR!

Tested

• Ethstats & blockscout working when on a dev testnet (celo-networks-dev kube cluster and the default VPC network)
• Ethstats & blockscout working when on a testnet with its own cluster & network

Other changes

I moved a lot of cluster setup logic out of celotooljs deploy initial testnet into a separate function so that deploy initial ethstats or deploy initial blockscout will perform the cluster setup if it hasn't been done already.

I also ran terraform fmt to format the terraform code

Backwards compatibility

All existing commands should be backwards compatible
