test: fix failing smoke tests (#400)

* test: update smoketest/run to depend on the correct task

fix file not found

* test: update to gcp-compute-optimized-v3

* test: use 1gb elasticsearch with 1 zone

the lambda extension is just sending a couple of requests, there's no need to use
a 8g instance.
This saves a bit more than 1m when running smoke tests
