Add Configurable Delay Buckets

Wire up delayed SNS topics. Maybe create a simple Lambda function that makes a delayed call to another SNS topic.

Let's start with 4 buckets and these delays: 1) Professional Trader: 0 delay 2) Active Day Trader: 2 minute delay 3) Hobbyist Day Trader: 4 minute delay 4) Just Watching: 15+ minute delay
