- Prevents `terraform destroy` from running against load test
infrastructure, for a given workspace, if an identical osquery perf
workspace exists.
- Adds a check to the osquery perf workflow, to fail fast, if the
specified load test infrastructure workspace is not detected.
- Adds ability for users to configure the osquery perf (increment -
`input.loadtest_containers_increment`) batch size that get deployed to
an environment during every loop. Default: 4.

## Summary by CodeRabbit
* **New Features**
* Added a configurable load-test container increment input (default: 4)
to control scaling increments.
* **Improvements**
* Prevented destructive runs when an existing infra workspace matches
the requested name.
* Tightened workspace-existence checks to require exact name matching.
* **Chores**
* Default load-test increment reduced from 8 to 4 and input validated as
a positive integer.
