Dump container logs on functional test failure (#9347)

## What changed?
- We now dump container logs for failing GHA runs (including for
cassandra and elasticsearch).

## Why?
- Debugging some flakiness in ES8 on ARM, right now the logs for
dependencies aren't available since the cluster is torn down at the end
of the test.

## How did you test it?
- [ ] built
- [ ] run locally and tested manually
- [ ] covered by existing tests
- [ ] added new unit test(s)
- [ ] added new functional test(s)
