Subject: [PATCH] Fix printing docker container logs

Currently, we observe non-readable artefacts in the beginning of each
log line from docker container because log stream prints logs in
multiplexed way and first 8 bytes is actually a header by default. This
patch fixes this issue by using TTY mode (in this case output data
is copied directly from the container output stream, no extra
multiplexing or headers)[1].
