Test notifications

The api is currently rejecting alarms with no action specified, so expect an error defining that alarm.
Setup alarms and Notifications
- run ./alarm_notification.py -e me@hp.com
Run the jmeter tests
- jmeter -t notification-jmeter.jmx &
- The config is saved for a basic test that should create a notification on alarm and a hundred non-notification alarms. Change the thread loop counts to try different combinations.
