Currently our terraform is designed to set up localstack. This diff splits the config into dev/ and remote/ directories, and moves the current config into dev/. This is so we can add remote/ and set up a remote AWS account.
Shared resources (DDB tables and S3 buckets) are held in modules/shared/ directory as a terraform module.

Also updated the AWS terraform provider - the old one was outdated

Set up localstack and make sure it was populated by terraform

cd services && yarn reset-local-cloud
awslocal dynamodb list-tables
