Notifications DB

[thiessenp-cds]

Add a new Notifications table to the DB. The table will store Notification key-value data used to send an email. Once a notification is sent, the related record can be deleted (not stored long term).

From the architecture diagram, the related changes are in green:

Notification Table is TBD but here is a first pass:

Key: notificationId
Note: for the case of a deferred notification, this Id will be used by the process that does additional work and later calls the Notification lambda with this Id to lookup the record.

Value (JSON) :

Name	Type	Required	Notes
emails	string[]	yes
subject	string	yes
body	string	yes	markdown email content body

DB is ready for review and moving on to creating the lambda.
