- Sets `filesystem` logging in loadtesting environment
- Updates fleet image to 4.76.0 as the default value
- Updates `migrations` and `logging_alb` modules with latest versions
- Removes `(Coming Soon)` from
`infrastructure/loadtesting/infra/README.md` with regards to deployment
via Github Actions
- Moves Signoz steps to `.header.md` to preserve steps in generated
`README.md`

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.

SigNoz converted from child module to standalone root module with
independent state.
**Critical Impact**
Deployment order is now required:
1. Deploy infrastructure/loadtesting/terraform/signoz/ FIRST
2. Then deploy infrastructure/loadtesting/terraform/infra/
Communication between modules via Terraform remote state.
**Key Configuration Changes**
- SigNoz creates its own EKS cluster: signoz-${workspace}
- Instance type: t3.xlarge (upgraded from t3.large for resource
headroom)
- ClickHouse disk: 200Gi (was 20Gi) with 2-day retention
- Resource limits configured to prevent OOMKills during loadtest
- wait_for_jobs = false to avoid Helm deployment deadlock

This PR allows us to run loadtest with SigNoz OTEL backend by adding
`-var=enable_otel=true`
SigNoz is deployed via Helm chart.
Enhancements needed (in future PR):
- put SigNoz UI behind VPN
- combine the new eks-vpc with shared fleet-vpc
- make SigNoz shared, so multiple loadtests use the same instance? (But
what about updating to it to latest version?)
Next steps:
- Enable SigNoz in Dogfood environment
- SigNoz by default [keeps 15 days of logs and
traces](https://signoz.io/docs/userguide/retention-period), which is
quite a bit. How much would that cost us and should we reduce it?
