Create script to dump mongodb and upload to S3

[mrcnc]

Let's snapshot the data in MongoDB periodically and then upload the db dump to S3 so we can have a backup in case anything were to happen on the server we're currently hosting this on.

Assume the script will be able to load AWS credentials from default location on the server (so no need to have credentials or environment variables for AWS keys).

The script should be able to run on some type of configurable cron schedule. Either cron on the server or as a container. I think once daily is fine for now, preferably at night.

Additionally the script should use set the bucket location using an environment variable
