Terminate terminal sessions on logout#

By default, when a user logs out, their open terminal sessions will remain active.

To disable this behavior:

Modify the /opt/wakari/wakari-server/etc/wakari/wk-server-config.json file:
```
"TERMINATE_TERMINALS_ON_LOGOUT": true,
```
Modify the /opt/wakari/wakari-gateway/etc/wakari/wk-gateway-config.json file:
```
"TERMINATE_TERMINALS_ON_LOGOUT": true,
```
Restart the AEN server service:
```
sudo service wakari-server restart
```
Restart the AEN gateway service:
```
sudo service wakari-gateway restart
```
