[HttpStress] [SslStress] Migrate to Compose plugin in Linux pipelines

[antonfirsov]

This is a follow up on #108703 which migrated from Compose standalone (docker-compose) to Compose plugin (docker compose) on Windows.

docker-compose is deprecated and broken in some environments, see docker/compose#11742. While it works on CI currently, it might lead to problems in developer inner loop. We should harmonize our scripts and yamls to use docker compose everywhere.
