Refactor instance-scheduler to make the code DRY

User Story

The instance scheduler supports RDS instances scheduling now, but there is a lot of code repetition. See if you can introduce a Instance interface type that will serve both EC2 and RDS clients and replace the common functions with methods. Note there is an equal amount of repetition in tests too. This will also need updating as we change the main code.
