If there is only one openconnect instance running, you can also use
killall or pkill.  The supported signals are listed in the man page.
Usually you'll want to use SIGINT for a clean disconnection.

If you're running multiple instances, it's probably easiest to use
something like "--pid-file /var/run/openconnect.foo" so you can easily
determine the PID for each connection.
