Title: Filter instances using EC2 API instead of locally

This change will allow EC2 API to filter by tags, AZ, and instance state. In the situation where you have a large number of instances/reservations, this can be a performance boost.

Note that we still do the security group filter locally due to the different strategies (all or some must match).
