Remove unnecessory -it from docker run command
Remove unnecessory -it from docker run command

We expect that storlets docker containers run in background,
so We don't need -i and -t to start them.
This patch removes these unnecessory options, and also fixes
some outdated comments in restart_docker_container script.
