Serverless collection solution to collect Duo security logs in to Sumo logic

Deprecation Notice This legacy solution to pull logs from Dup to Sumo Logic has been replaced with a dedicated Cloud-to-Cloud Integration Framework source. We recommend customers use the Duo Cloud-to-Cloud source instead of this legacy Python collection method.
