big.cdr.dev was originally provisioned using the Terraform configuration under scaletest. There have been some changes since then, including but not limited to:

• cert-manager, TLS, etc.
• otel-collector

Bring the terraform up to date so that subsequent environments created with the same terraform have a similar configuration:

• Refactor the existing configuration to remove reliance on null_resource and ensure idempotency
• Update existing configuration to bring it in line with what is currently deployed at big.cdr.dev
• Add missing configuration for big.cdr.dev: otel-collector, cert-manager etc.
