Do not kill docker container with SIGKILL
Do not kill docker container with SIGKILL

When we will use `kill` command on `docker` main process will receive
`SIGKILL` signal. This will result in immediate termination of
processes. We need to send a signal `SIGTERM` to main process and give
the opportunity to close application in correct way.
