* feat: allow scaling down scaletest environments
* fix bugged namespace deletion
* misc fixes to scaletest.sh
* destroy namespaces is a no-op as the cluster will be gone anyway
* chore: scaletest: plumb through more options
* bump terraform version
* scaletest.sh: pprof during traffic gen
* cli/scaletest: actually wait for prometheus metrics to be scraped
* increase prometheus wait
- Adds a convenience script `scaletest.sh` to automate process of running scale tests
- Enables pprof endpoint by default, and captures pprof traces before tearing down infra.
- Improves idempotency of coder_init.sh
- Removes the promtest.Float64 invocations in workspacetraffic runner, these metrics will be in prometheus.
