Feature Request: Alert Event Handler for AWS SNS or Kinesis

An AWS SNS or Kinesis handler for alert events would allow for very flexible handling of alert events by processing these events with a Lambda function.

No files, tests, or entry points are named. Begin by locating Kapacitor’s alert-event handler extension points and reviewing the requirements for delivering events through AWS SNS or Kinesis to a Lambda function. Done would require an agreed scope and a working, tested handler.
