Use t2.medium as default for EC2 instance type used by the auto scaling group since Terraform recommends at least 4 GB of RAM here. This would address some failing executions due to memory issues while using the previous t2.micro instance type. Also added the capability to override this parameter.
Testing:
Updated TRE to use t2.medium and provision, update, terminate operations succeed after the update
