Is your feature request related to a problem? Please describe:

After a build has started or finished, I would like to receive its jobId in an SNS notification, so that I can poll the job's commit message and send it to Slack

Describe how you'd like this feature to work

Just add the jobId somewhere in the SNS payload (it was present in previous Amplify projects but was removed when I created a new Amplify project)
