:Description:
Adds support for SNS notifications. SNS notifications (like other notification plugins) are currently only supported
for certificate expiration. Configuration requires a region, account number, and SNS topic name; these elements
are then combined to build the topic ARN. Lemur must have access to publish messages to the specified SNS topic.

------------
Lemur includes the ability to create Email notifications by **default**. These notifications
currently come in the form of expiration notices. Lemur periodically checks certifications expiration dates and
currently come in the form of expiration and rotation notices. Lemur periodically checks certificate expiration dates and
determines if a given certificate is eligible for notification. There are currently only two parameters used to
determine if a certificate is eligible; validity expiration (date the certificate is no longer valid) and the number
of days the current date (UTC) is from that expiration date.
There are currently two objects that available for notification plugins the first is `NotficationPlugin`. This is the base object for
any notification within Lemur. Currently the only support notification type is an certificate expiration notification. If you
Expiration notifications can also be configured for Slack or AWS SNS. Rotation notifications are not configurable.
Notifications sent to a certificate owner and security team (`LEMUR_SECURITY_TEAM_EMAIL`) can currently only be sent via email.
There are currently two objects that are available for notification plugins. The first is `NotificationPlugin`, which is the base object for
any notification within Lemur. Currently the only supported notification type is a certificate expiration notification. If you
are trying to create a new notification type (audit, failed logins, etc.) this would be the object to base your plugin on.
You would also then need to build additional code to trigger the new notification type.
The second is `ExpirationNotificationPlugin`, this object inherits from `NotificationPlugin` object.
