[Feat]: Alerting for when AccountFileProcessorFunction fails

[faridnsh]

Describe the feature

It would be ideal in the future that when AccountFileProcessorFunction has failed, a slack message or an email is sent out so we know that something is wrong.

Use Case

With #728 happening it took us sometime to realize something was wrong, it would be nice to know it as soon as it happens.

Proposed Solution

Cloudwatch alarm with some mechanism to send a notification via existing email or slack configuration
