Update with small/large scenarios

Problem Description: Often the multi-bin scenario inadvertently triggers spin up of larger backend instances for the hybrid solver, which can cause a wait time of ~10 minutes. We usually have to keep a list of "good" settings for interesting scenarios handy on the side so that we know how to set all of the options smoothly during a live demo.

Additionally, the defaults when the demo opens do not provide an interesting initial scenario to run. It may be confusing to new developers to try and find "interesting" scenarios when they are first exploring this demo.

Solution: Provide example scenarios for a few instances that are interesting (single bin, 2 bins, etc). This could be done in an optional drop down that pre-fills the settings to that scenario. This would help new users explore the demo with some guidance to start, as well as provide a more seamless experience in live demo environments for tech sales and others presenting this demo.

This has been requested a couple times now so I'm adding it as a medium priority.
