restart_services.sh: restart pipeline service when .env file changes

Environment variable `KCI_API_TOKEN` is required to run
pipeline services. The variable is defined in `.env` file.
Add a script to monitor `.env` file. If the file changes
are detected, that is if the token is modified, restart
all the services.
