Custom notifier messages

[DanielHouston]

It would be great to customize SMS, Email and HipChat notifications with custom templates. Looking particularly at SMS alerts, there are clear variables (Service name, namespace, cluster, state) around which you could build custom messages.

Current: Service [myservice] for [demo@cluster] is in "CRITICAL" state

With a template stored in the cluster named SMS_TEMPLATE or something:
Searchlight monitoring has triggered: Your Service %service_name% in namespace %ns% on cluster %cluster% is in %state% state

resulting in:
Searchlight monitoring has triggered: Your Service "myservice" in namespace "demo" on cluster "cluster" is in CRITICAL state

Similarly, a HTML template could be used for emails

From my understanding of the codebase; making sms.go etc configurable based on a template wouldn't be too hard. The difficulty would be in exposing that configuration to the user while maintaining a simple deployment (as it's all compiled and shipped as a container.)
