Mehdi Abaakouk d62fbc9b49 Separate alarm storage models from other models
This change isolate storage models used for alarm into a separate file.

This a preparation work to have all alarms related storage API inside
the alarm namespace and then be able to have a different database for
alarming and metering.

Partial implements blueprint dedicated-alarm-database
