Azat Khuzhin ebc61a36e0 tests/stress: improve OOM detection (add separate check by dmesg) 
Right now if you will look at the OOM errors:
- OOM killer (or signal 9) in clickhouse-server.log
- Backward compatibility check: OOM messages in clickhouse-server.log

Most of them are not real, but just clickhouse server got KILLed by
clickhouse stop, #40678 may imporove the situation, but to definitely
sure that there was OOM let's look at dmesg.

Allow to run simple ClickHouse stress test in Docker from debian packages. Actually it runs multiple copies of clickhouse-test (functional tests). This allows to find problems like segmentation fault which cause shutdown of server.

Usage:

$ ls $HOME/someclickhouse
clickhouse-client_18.14.9_all.deb clickhouse-common-static_18.14.9_amd64.deb clickhouse-server_18.14.9_all.deb
$ docker run --volume=$HOME/someclickhouse:/package_folder --volume=$HOME/test_output:/test_output clickhouse/stress-test
