Terraform changes after my latest loadtest.
VPC consolidation: updated (and deployed) shared VPC so that Signoz
backend can now use it
- Removed eks-vpc/ directory
- Moved VPC management to shared/vpc.tf
- Updated shared/init.tf to reflect VPC changes
Infra improvements
- infra/internal_alb.tf - changed suffix from -internal to -int since I
hit max 32 characters issue
OTEL
- OTEL Collector configuration overrides for production stability
untested end-to-end but works as a replacement for plans and doesn't
require a local arm64 build to work.
