CI-5400 Collect logs for tests even if they hang

[uaqq]

Collect logs for tests even if they hang (#4)

• update behave and regression tests workflow;
• add CI condition for behave tests (do not stop containers in CI).
• remove legacy log collection from ci/scripts/run_behave_tests.bash;
• remove behave_collect_logs.bash script;
• fix sql dump artifact name.

Introduce a composite action to collect logs from containers,
even for failed or canceled test runs.

Implementation details

• iterate over Docker containers on the host;
• execute log collection inside each container.
