module AlertManagement
# Module to support the processing of new alert payloads
# from various sources. Payloads may be for new alerts,
# existing alerts, or acting as a resolving alert.
#
# Performs processing-related tasks, such as creating system
# notes, creating or resolving related issues, and notifying
# stakeholders of the alert.
#
# Requires #project [Project] and #payload [Hash] methods
# to be defined.
