[FEATURE] Return trigger condition information in bucket level ctx for notification messages

[AWSHurneyt]

Is your feature request related to a problem?
Currently, bucket level triggers do not expose trigger condition information in the asTemplateArgs function. This prevents notification messages from including that info.

What solution would you like?
Expose trigger condition information in ctx of the trigger. This information can be helpful for consumers of notifications for determining what actions to take to resolve an alert.
